I’ve almost completed development of my first integration.
It’s reads data from Mobile Alerts / TFA WeatherHub devices as it described here: GitHub - sarnau/MMMMobileAlerts: Documentation about the protocols of ELV Mobile Alerts sensors plus a node MQTT gateway and an Arduino UDP gateway
The integration has a config flow and DHCP discovery.
My next goal is to pull it to HA main repository, but for now I need beta testers. I don’t like to publish it via HACS for now.
Test it please if you can.
