This package listens for local data from Ambient Weather stations (such as the WS-2902C) and converts the incoming data to MQTT events. The sensor data is published with auto-discovery so they show up automatically as sensors in Home Assistant.
The following Ambient Weather station models are confirmed to work:
- WS-2902C
The package is provided as a Docker image for ease of installation. The sampleConfiguration folder contains the two files necessary for setup.
- Copy the sampleConfiguration/.env and sampleConfiguration/docker-compose.yml file to your local machine.
- Edit the
.env
file and specify the required information. At a minimum you must provide the address of your MQTT server, your Ambient Weather station's MAC address, and the timezone your station is located in. The sample.env
contains comments explaining the additional options available including username and password for connecting to the MQTT server. - Start up the service by running
docker-compose up
in the same folder as two downloaded configuration files.
If the server starts up successfully you will see log messages like this:
2021-06-30T05:59:56-07:00 [Main] Starting up
2021-06-30T05:59:56-07:00 [MQTT] Connected to MQTT server http://192.168.1.172:1883
2021-06-30T05:59:56-07:00 [Web server] Listening at http://localhost:8080
Installation
Add https://github.com/neilenns/ambientweather2mqtt
as an add-on repository.
Your Ambient Weather station must be configured to send data to the local service. This configuration is done through the awnet
app. It is recommended to use an iOS device, but some have found success using an Android device as well.
- Run the
awnet
app and connect to your weather station. - Tap
next
through the configuration screens until you get to theCustomized
screen. - Set the fields to the values in the following table.
- Tap
Save
.
Field | Value | Notes |
---|---|---|
Enable/Disable | Enable | Make sure to set this to Enable otherwise no data will get sent. |
Protocol Type Same As | Ambient Weather or Weather Underground | Ambient Weather supports more sensor data and is preferred. Select Weather Underground only if using a weather station that doesn't support Ambient Weather. |
Server IP / Hostname | The IP or hostname for the machine running the Docker container | |
Path | /data/? |
It is very important this field is entered exactly as shown. Be very careful to include the ? at the end otherwise nothing will work. |
Station ID | Any non-blank value | Only required when the protocol is set to Weather Underground. The actual value provided doesn't matter but something must be in the field. |
Station Key | Any non-blank value | Only required when the protocol is set to Weather Underground. The actual value provided doesn't matter but something must be in the field. |
Port | The port specified in the .env file |
If running in Home Assistant this should be set to 7000 . If running the standalone Docker image the sample .env file provided uses 8132 so unless you changed it to something else you should enter 8132 here. |
Upload Interval | The frequency to send the data. | 30 is a reasonable value to start with. |
Here is what a properly configured weather station looks like:
To verify everything works connect to your Home Assistant server and go to Configuration > Devices and search for ambientweather2mqtt. You should see a list of all the sensors with current values reported.
If you see the list of sensors but they all report Unavailable
for the value it
means the data from the weather station is not being received by this system.
Check the following:
- The
Server IP / Hostname
value was set to the correct IP address for the Docker system. - The
Port
value was set to the same value specified in.env
. - The
Path
value was set to/data/?
with the question mark at the end. If the question mark is missing the system will not work. - Your firewall rules aren't blocking communication from your weather station to your Docker server. This can happen if you run virtual LANs to segment NoT/IoT traffic from your primarily LAN.
The following sensors are supported. Note that weather stations will only report the subset of these they support.
