@revk What device do you use to monitor the temp?

@talldavek A Xiaomi BLE sensor reflashed with open source TeLink code and picked up using my own ESP32 code monitors.

@revk I'm glad I'm not the only one! Yours seems to be doing better than mine, though.

@philpem @revk Which sensors are you all using?
Show threadPhil M0OFXMar 13
@tk @revk I'm using some cheap 433MHz triple-sensor kit which came from Amazon. Three's an ESP8266 in the garage running the Nexus protocol receiver and rebroadcasting it to Home Assistant.
I've opened a PR on ESPHome to add the Nexus protocol support but it's had zero interest from any of the devs.
