I made a few AirGradient air quality sensors and loaded ESPHome onto the ESP8266’s. They have entity IDs of sensor.humidity, sensor.humidity_2, etc. I’d like to rename them to sensor.roomname.humidity. Searching tells me to do that in Configuration>Entities but when I try, HA returns “Invalid entity ID.” Same thing happens in Developer Tools>States>sensorname. This is really stumping me - what am I overlooking? Thanks!
