Note it does 16 but they've been promising a code update that will handle more than 1 ( i have 29 circuit breakers). I could likely install the 2nd one I bought without the update but I am waiting. The price is incredible at 129 I've seen most at much higher prices and dont have MQTT.
I have since completely redid the code with several Docker containers.
The unit sends MQTT messages but every 2 seconds.
I have a python script that only sends to the mqtt broker when things have changed by 5% which reduces the traffic into Hubitat a lot. Hubitat did not like the every 2 secs. It also sends to InFluxDB for use by Granfana Local and also sends to Grafana Cloud.
