I noticed under MQTT you can have a sensor with the class of ‘Battery’, this is nice because the icon changes based on the value.
I have created a ESP8266 device that reports its own WiFi signal strength, this is published to MQTT. It would be great to have a WiFi RSSI class that measures in ‘dBm’ and changes the icon based on strength.
The negative value of dBm is somewhat confusing for basic users.
I think signal displayed with the bars might be helpful
Is this worth while?
