The ATC firmware puts all relevant data into these beacons. But this is not necessary at all.īluetooth Low Energy sends advertising beacons every few seconds. This means it will actively poll each registered device. There is an official Home Assistant integration, but that works in active mode. So if your device's Bluetooth name is ATC123456, its MAC is A4:C1:38:12:34:56. The 6 characters in the name are the last 3 bytes of the device's MAC address. Click connect again to find the new device and physically label the sensor accordingly to avoid confusion later. Tip: after flashing the device, it will change it's Bluetooth name to ATC followed by 6 letters/digits. Once the repository is added to HACS, installed and HA is restarted, the integration can be added in the configuration and a few seconds later all the beautiful weather data will start flowing into your Home Assistant. I'm currently using the 0.0.7 beta release of PoppyPop's fork. But thanks to the magic of OpenSource, there are forks available with all the necessary fixes needed. Unfortunately the Ecowitt Weather Station integration for home-assistant by has a couple of unfixed bugs and isn't working in current HA setups. Next, a custom integration that speaks the Ecowitt protocol is needed. There simply select the Ecowitt protocol, use the IP address of your Home Assistant instance and set the path and port to / and 4199 respectively. Instead of registering at any of the commercial services, use the next button until you reach the “Customized” tab. Once the hardware is assembled, you need to use their (ugly) app to configure the WiFi and the services it shall send the data to. Luckily, many of the stations also allow you configure a custom server, so that's the way I went.

For my home setup I prefer my sensors to work locally if possible. Īfter some more research, I found that many of the cheaper WiFi weather stations work with the online services Weather Underground or EcoWitt. But the full system with rain and wind sensors is over 300 EUR. It seems the Netatmo System is relatively well supported out of the box. It was surprisingly hard to find a straight answer on what weather station to buy, if you want an easy integration with Home Assistant. And of course, when I put a sensor for humidity outside, why not a whole weather station? The first step is to know the humidity outside.
