# Integrates your Sencor SWS 12500, SWS16600, SWS 10500, GARNI, BRESSER weather stations seamlessly into Home Assistant
|
||
|
||
This integration will listen for data from your station and passes them to respective sensors. It also provides the ability to push data to `Windy API` or `Pocasi Meteo`.
|
||
|
||
### Ecowitt support
|
||
|
||
Ecowitt stations are supported as of the pre-release version
|
||
[v2.0.0pre1](https://github.com/schizza/SWS-12500-custom-component/releases/tag/v2.0.0pre1).
|
||
You can download this pre-release in HACS under `target version`, where you can pick the exact
|
||
version of the integration. Please be aware that this pre-release is really for testing
|
||
purposes only.
|
||
|
||
See [Ecowitt stations](#ecowitt-stations) for the setup steps.
|
||
|
||
---
|
||
|
||
### Integration rename is planned for the next major release
|
||
|
||
The current name no longer reflects what the integration does. It was initially developed
|
||
primarily for the SWS 12500 station, but it already supports other weather stations as well
|
||
(Bresser, Garni, Ecowitt and others) — so the current name has become misleading. The
|
||
transition will be announced via an update, and I'm also planning to offer a full data
|
||
migration from the existing integration to the new one, so you won't lose any of your
|
||
historical data.
|
||
|
||
- The transition date hasn't been set yet, but it's currently expected to happen within the
|
||
next ~2–3 months. At the moment, I'm working on a full refactor and general code cleanup.
|
||
Looking further ahead, the goal is to have the integration fully incorporated into Home
|
||
Assistant as a native component — meaning it won't need to be installed via HACS but will
|
||
become part of the official Home Assistant distribution.
|
||
|
||
- I'm also looking for someone who owns an Ecowitt weather station and would be willing to
|
||
help with testing the integration for these devices.

## Warning — WSLink app (applies also to SWS 12500 with firmware > 3.0)
|
||
|
||
Please read the **IMPORTANT** note below.
|
||
|
||
For stations that use the WSLink app to set up the station and the WSLink API for resending
|
||
data (also SWS 12500 stations manufactured in 2024 or later), you will need to install the
|
||
[WSLink SSL proxy add-on](https://github.com/schizza/wslink-addon) into your Home Assistant
|
||
— unless you are already running Home Assistant in SSL mode or you have your own SSL proxy
|
||
in front of Home Assistant.
|
||
|
||
---
|
||
|
||
> [!IMPORTANT]
|
||
> The recommendation above does not apply to all stations. As is known by now, some stations
|
||
> — even when configured via the `WSLink App` — do not use the `WSLink protocol` to send
|
||
> data to custom servers. It can therefore be confusing how to configure your station, and
|
||
> for that case I made a simple debugging server (see below).
|
||
|
||
## Not Sure How Your Station Sends Data?
|
||
|
||
If you are struggling with configuration and don't know which protocol your station uses (`WSLink` or `PWS/WU`), or whether it sends data over SSL or plain HTTP — use our public test server:
|
||
|
||
**<https://test-station.schizza.cz>**
|
||
|
||
1. Open the link above and create a new session.
|
||
2. Point your weather station to the generated subdomain address.
|
||
3. Within a few seconds the server will show you:
|
||
- the **protocol** your station is using (`WSLink` or `PWS/WU`)
|
||
- whether the request arrived over **SSL** or **non-SSL**
|
||
- the full query string, headers, and payload your station sent
|
||
|
||
This information tells you exactly how to configure the integration in Home Assistant.
|
||
|
||
### Quick Recommendations
|
||
|
||
| Station sends via | Protocol | Recommended Setup |
|
||
|---|---|--- |
|
||
| **plain HTTP** | PWS/WU | Point the station directly at Home Assistant — no proxy needed. Keep `WSLink API` unchecked (disabled). |
|
||
| **plain HTTP** | WSLink | Point the station directly at Home Assistant — no proxy needed. Enable `WSLink API` in settings. |
|
||
| **HTTPS (SSL)** | PWS/WU | Install the [WSLink Proxy Add-on](https://github.com/schizza/wslink-addon) — it terminates TLS and forwards plain HTTP to Home Assistant. Keep `WSLink API` unchecked (disabled). |
|
||
| **HTTPS (SSL)** | WSLink | Install the [WSLink Proxy Add-on](https://github.com/schizza/wslink-addon) — it terminates TLS and forwards plain HTTP to Home Assistant, and enable `WSLink API`. |
|
||
|
||
— If the test server shows your station is sending over SSL, you need the [WSLink Proxy Add-on](https://github.com/schizza/wslink-addon). If it sends plain HTTP, you can connect directly.

||
Web server repo is reachable here: <https://github.com/schizza/test-station-server>
|
||
|
||
## Requirements
|
||
|
||
- Weather station that supports sending data to custom server in their API [(list of supported stations.)](#list-of-supported-stations)
|
||
- Configure station to send data directly to Home Assistant.
|
||
- If you want to push data to Windy, you have to create an account at [Windy](https://stations.windy.com).
|
||
- If you want to resend data to `Pocasi Meteo`, you have to create accout at [Pocasi Meteo](https://pocasimeteo.cz)
|
||
|
||
## Examples of supported stations
|
||
|
||
- [Sencor SWS 12500 Weather Station](https://www.sencor.cz/profesionalni-meteorologicka-stanice/sws-12500)
|
||
- [Sencor SWS 16600 WiFi SH](https://www.sencor.cz/meteorologicka-stanice/sws-16600)
|
||
- SWS 10500 (newer firmware revisions are also supported via the [WSLink SSL proxy add-on](https://github.com/schizza/wslink-addon))
|
||
- Bresser stations that support custom server upload — [this model is known to work](https://www.bresser.com/p/bresser-wi-fi-clearview-weather-station-with-7-in-1-sensor-7002586), for example
|
||
- Garni stations with WSLink support or custom server support
|
||
- Ecowitt stations that support the `Customized` / `Ecowitt` upload protocol — see
|
||
[Ecowitt stations](#ecowitt-stations)
|
||
- and a bunch of other models that aren't listed here are also supported
|
||
|
||
## Supported sensors
|
||
|
||
The integration auto-creates sensors as soon as the station first sends data for them — new
|
||
sensors trigger a notification in Home Assistant and are added to the entity list
|
||
automatically. Only the fields your station actually sends are created, so an entry never
|
||
shows entities for probes you do not own.
|
||
|
||
### WSLink — complete API coverage
|
||
|
||
**Every measurement the WSLink data upload API (v0.6) defines is implemented**, across all
|
||
of its sensor types. Readings are mapped to native Home Assistant device classes, so
|
||
statistics, unit conversion and the energy/weather dashboards work without any template
|
||
helpers.
|
||
|
||
| Sensor type | Readings |
|
||
| --- | --- |
|
||
| Console | indoor temperature and humidity, relative **and absolute** barometric pressure, console battery |
|
||
| **Type1** outdoor | temperature, humidity, dew point, **feels-like**, heat index, wind chill, **WBGT**, wind direction / speed / **10-minute average** / gust, rain rate and hourly / daily / weekly / monthly / yearly totals, UV index, solar irradiance, battery |
|
||
| **Type2/3/4** CH2–CH8 (API CH1–CH7) | temperature and humidity per channel, battery |
|
||
| **Type5** lightning | distance, time since the last strike, strike counts over 5 min / 30 min / 1 h / 1 day, battery |
|
||
| **Type6** water leak CH1–CH7 | leak state per channel (entities `leak_ch1` – `leak_ch7`), battery |
|
||
| **Type8** particulate matter | PM2.5, PM10 and their AQI values, battery |
|
||
| **Type9** air quality | formaldehyde (HCHO) in ppb, VOC level, battery |
|
||
| **Type10** | CO₂ concentration, battery |
|
||
| **Type11** | CO concentration, battery |
|
||
|
||
A few details worth knowing:
|
||
|
||
- **Channel numbering differs between the two multi-channel families.** For historical
|
||
reasons the temperature/humidity channels are numbered one higher than the API numbers
|
||
them, so WSLink `CH1` is the `ch2_*` entity ("Channel 2 temperature") and WSLink `CH7`
|
||
is `ch8_*`. The water leak channels are not shifted: WSLink `CH1` is `leak_ch1`.
|
||
- **There are two 1-hour lightning counters.** The API defines both `t5lsf` ("strike
|
||
count last 1 hours") and `t5ls1htc` ("count total of during 1 hour") without saying how
|
||
they differ, so both get an entity and both carry the parameter name, rather than the
|
||
integration guessing which one your firmware fills in.
|
||
- **Batteries come in two kinds, and they are not interchangeable.** The outdoor, channel,
|
||
lightning and water-leak probes report a plain `normal` / `low` flag and become binary
|
||
`battery` sensors. The PM, air-quality, CO₂ and CO probes report a 0–5 level instead and
|
||
become percentage sensors (5 = full). The mapping follows the API document literally and
|
||
is enforced by tests, because a level battery read as a flag would silently report
|
||
"not low" for everything above empty.
|
||
- **Probes are gated on their connection flag.** A probe the station reports as
|
||
disconnected has its readings dropped rather than left frozen at the last value. A
|
||
station that does not send a connection flag, or sends it empty, is never gated — only an
|
||
explicit "not connected" drops readings, because a missing flag is not evidence of a
|
||
disconnection.
|
||
- **A soil probe is not a humidity sensor.** WSLink reports what kind of probe sits on each
|
||
channel, so a soil moisture & temperature probe gets Home Assistant's `moisture` device
|
||
class instead of `humidity`. The reported probe types are remembered across restarts, and
|
||
the class is resolved when the entity is created; swapping the physical probe on a channel
|
||
therefore takes effect on the next restart, once the station has reported the new type.
|
||
- **VOC level** is reported as a named air-quality level (`unhealthy`, `poor`, `moderate`,
|
||
`good`, `excellent`) from the station's 1–5 index, where 1 is worst.
|
||
- **Heat index and wind chill** are taken from the station when it sends them, and computed
|
||
from temperature, humidity and wind speed when it does not.
|
||
- Battery sensors used to be regular sensors. On an upgraded install the old entities are
|
||
left behind; a `Repairs` issue lists them and tells you how to remove them.
|
||
|
||
Two parameters are exposed with a caveat, because the API document does not define them
|
||
fully: the console battery (`inbat`) is the only battery whose scale is not documented and
|
||
is treated as a `normal` / `low` flag, and the time since the last lightning strike
|
||
(`t5lst`) is read as minutes, with the vendor's `9999` treated as "nothing recorded".
|
||
|
||
### Ecowitt
|
||
|
||
Ecowitt stations map onto the same standard set and additionally report whatever their own
|
||
firmware sends — absolute pressure, event / hourly / weekly / monthly / yearly / total /
|
||
24h rain, feels-like temperature, indoor dew point and CO₂ readings among them. Readings
|
||
the integration has no mapping for still get an entity, so a newer firmware does not need
|
||
an integration update to be usable.
|
||
|
||
### Diagnostics
|
||
|
||
The integration also creates diagnostic entities describing its own state — the active
|
||
protocol, whether each endpoint is registered, details of the last received payload, the
|
||
status of the WSLink proxy add-on, and the state of the Windy / Pocasi Meteo forwarders.
|
||
They are grouped under `Diagnostic` on the device page, and the same data is included in
|
||
the config entry's `Download diagnostics` file.
|
||
|
||
## Installation
|
||
|
||
### For stations that send data through WSLink API
|
||
|
||
Make sure you have your Home Assistant configured in SSL mode or use [WSLink SSL proxy addon](https://github.com/schizza/wslink-addon) to bypass SSL configuration of whole Home Assistant.
|
||
|
||
### HACS installation
|
||
|
||
For installation with HACS, you have to first add a [custom repository](https://hacs.xyz/docs/faq/custom_repositories/).
|
||
You will need to enter the URL of this repository when prompted: `https://github.com/schizza/SWS-12500-custom-component`.
|
||
|
||
After adding this repository to HACS:
|
||
|
||
- Go to HACS -> Integrations
|
||
- Search for the integration `Sencor SWS 12500 Weather station` and download the integration.
|
||
- Restart Home Assistant
|
||
- Now go to `Integrations` and add new integration. Search for `Sencor SWS 12500 Weather station` and select it.
|
||
|
||
### Manual installation
|
||
|
||
For manual installation you must have access to your Home Assistant's `/config` folder.
|
||
|
||
- Clone this repository or download the [latest release here](https://github.com/schizza/SWS-12500-custom-component/releases/latest).
|
||
|
||
- Copy the `custom_components/sws12500` folder to your `config/custom_components` folder in Home Assistant.
|
||
- Restart Home Assistant.
|
||
- Now go to `Integrations` and add new integration `Sencor SWS 12500 Weather station`
|
||
|
||
## Configure your station in AP mode
|
||
|
||
> This configuration example is for Sencor SWS12500 with FW < 3.0
|
||
|
||
> For WSLink read [this notes.](#wslink-notes)
|
||
|
||
1. Hold the Wi-Fi button on the back of the station for 6 seconds until the AP will flash on the display.
|
||
2. Select your station from available APs on your computer.
|
||
3. Connect to the station's setup page: `http://192.168.1.1` from your browser.
|
||
4. In the third URL section fill in the address to your local Home Assistant installation.
|
||
5. Create new `ID` and `KEY`. You can use [online tool](https://randomkeygen.com) to generate random keys. _(you will need them to configure integration to Home Assistant)_
|
||
6. Save your configuration.
|
||
|
||
|
||
Once the integration is added to Home Assistant, the first dialog asks which type of
|
||
station you have. Choose `PWS/WSLink (Sencor, Garni, Bresser, other - Weather Underground
|
||
compatible)` — for Ecowitt stations see [Ecowitt stations](#ecowitt-stations) instead.
|
||
|
||
The next dialog asks for `API_ID` and `API_KEY` as you set them in your station:
|
||
|
||
```plain
|
||
API_ID: ID in station's config
|
||
API_KEY: PASSWORD in station's config
|
||
```
|
||
|
||
|
||
|
||
If you change `API ID` or `API KEY` in the station, you have to reconfigure integration to accept data from your station.
|
||
|
||
- In `Settings` -> `Devices & services` find SWS12500 and click `Configure`.
|
||
- In dialog box choose `Basic - configure credentials for Weather Station`
|
||
|
||
|
||
|
||
As soon as the integration is added into Home Assistant it will listen for incoming data from the station and starts to fill sensors as soon as data will first arrive.
|
||
|
||
## Ecowitt stations
|
||
|
||
Ecowitt stations do not use the `API ID` / `API KEY` pair — they are authorized by a
|
||
secret webhook ID that the integration generates for you.
|
||
|
||
- When adding the integration, pick `Ecowitt` in the station-type dialog. For an entry
|
||
that already exists, go to `Settings` -> `Devices & services` -> SWS12500 ->
|
||
`Configure` and choose `Ecowitt configuration`.
|
||
- The dialog shows the endpoint your station has to post to and pre-fills a freshly
|
||
generated webhook ID:
|
||
|
||
```plain
|
||
<your Home Assistant host>:<port>/weatherhub/<webhook_id>
|
||
```
|
||
|
||
- Enter that path as the custom-server path in the Ecowitt app (`WS View` / `Customized`
|
||
upload), keep the protocol on `Ecowitt`, and tick `Enable Ecowitt station data`.
|
||
|
||
> [!IMPORTANT]
|
||
> The legacy PWS/WSLink endpoint and the Ecowitt endpoint cannot be enabled at the same
|
||
> time — both feed the same sensor entities, which would mix up units and blank out
|
||
> readings. The config flow refuses to enable one while the other is on. Picking
|
||
> `Ecowitt` when you first add the integration turns the legacy endpoint off for you; to
|
||
> switch back, disable Ecowitt first and then tick `Enable PWS/WSLink endpoint` under
|
||
> `Basic - configure credentials for Weather Station`.
|
||
|
||
## Upgrading from PWS to WSLink
|
||
|
||
If you upgrade your station — which was previously sending data in the PWS protocol — to a
|
||
station that uses the WSLink protocol, you have to remove the integration and reinstall it.
|
||
The WSLink protocol uses the metric scale instead of the imperial scale used in PWS, and
|
||
deleting and reinstalling the integration makes sure the sensors are aware of the change of
|
||
measurement scale.
|
||
|
||
- because sensor unique IDs stay the same, you will not lose any of your historical data
|
||
|
||
## Resending data to Windy API
|
||
|
||
- First of all you need to create account at [Windy stations](https://stations.windy.com).
|
||
- Once you have an account created, open
|
||
[your stations](https://stations.windy.com/stations) and copy the **station ID** and the
|
||
**station password** of the station you want to feed.
|
||
|
||
|
||
- In `Settings` -> `Devices & services` find SWS12500 and click `Configure`.
|
||
- In dialog box choose `Windy configuration`.
|
||
|
||
|
||
- Fill in `Station ID obtained form Windy` and `Station password obtained from Windy`.
|
||
Both are required — enabling the forwarder with either one empty is rejected.
|
||
- Tick `Enable resending data to Windy`.
|
||
|
||
|
||
- You are done.
|
||
|
||
If Windy rejects the data three times in a row, the integration disables resending on its
|
||
own, writes the reason to the log and raises a persistent notification — fix the
|
||
credentials and tick `Enable resending data to Windy` again.
|
||
|
||
## Resending data to Pocasi Meteo
|
||
|
||
- If you are willing to use [Pocasi Meteo Application](https://pocasimeteo.cz) you can enable resending your data to their servers
|
||
- You must have account at Pocasi Meteo, where you will recieve `ID` and `KEY`, which are needed to connect to server
|
||
- In `Settings` -> `Devices & services` find SWS12500 and click `Configure`.
|
||
- In dialog box choose `Pocasi Meteo configuration`.
|
||
- Fill in `ID` and `KEY` you were provided at `Pocasi Meteo`.
|
||
- Optionally adjust `Resend interval in seconds` (minimum 12s, default 30s).
|
||
- Tick `Enable resending data to Pocasi Meteo`.
|
||
|
||
- You are done.
|
||
|
||
As with Windy, three unexpected responses in a row switch resending off automatically, log
|
||
the reason and raise a persistent notification. The `Forwarding to Počasí Meteo` and
|
||
`Forwarding status to Počasí Meteo` diagnostic sensors show the current state.
|
||
|
||
## WSLink notes
|
||
|
||
If your station sends WSLink data over SSL (see the
|
||
[Quick Recommendations](#quick-recommendations) table above), Home Assistant has to be
|
||
reachable over SSL too — either by running Home Assistant in SSL mode, or by putting it
|
||
behind an SSL proxy. You can bypass whole-system SSL setup by using the
|
||
[WSLink SSL proxy add-on](https://github.com/schizza/wslink-addon), which is made exactly
|
||
for this integration to support WSLink on non-SSL installations of Home Assistant.
|
||
|
||
### Configuration
|
||
|
||
- Set your station up as [described above](#configure-your-station-in-ap-mode), but for
|
||
`HA port` use the port the add-on is listening on — **not** the port of your Home
|
||
Assistant instance.
|
||
|
||
The add-on listens on port `443` by default. The example below uses `4443` to show what a
|
||
remapped port looks like — you would pick a port like that only if you changed the add-on's
|
||
port mapping, for instance because `443` is already taken on the host.
|
||
|
||
```plain
|
||
Home Assistant is at 192.168.0.2:8123
|
||
WSLink proxy add-on has been remapped to port 4443
|
||
|
||
→ set the station URL to: 192.168.0.2:4443
|
||
```
|
||
|
||
- Your station will send data to the SSL proxy and the add-on will handle the rest.
|
||
|
||
_Most stations do not care about self-signed certificates on the server side._
|
||
|
||
### Add-on health monitoring
|
||
|
||
The integration probes the add-on's health endpoint so the diagnostic entities can report
|
||
whether the proxy is online, which version it runs and which ports it uses. It has to know
|
||
the port to reach it on:
|
||
|
||
- In `Settings` -> `Devices & services` find SWS12500, click `Configure` and choose
|
||
`WSLink add-on port`.
|
||
- Set it to the same port the add-on listens on — the one you pointed the station at
|
||
above. This option defaults to `443`, which matches the add-on's own default, so you
|
||
only need to change it if you remapped the add-on's port (`4443` in the example above).
|
||
|
||
This setting only affects the health probe; incoming station data is unaffected by it.
|
