I want to integrate my new Shelly H&T sensor to Home Assistant (running Hass.io on Raspberry Pi) and, therefore, want to set up a MQTT broker. I have tried to set up the Mosquitto MQTT broker and to integrate the Shelly H&T sensor in Home Assistant but I am a bit overwhelmed. Could somebody help me through the debugging process step by step?
At First, I went to Home Assistant frontend → Hass.io tab → Add-on store → and installed the Mosquitto broker. Then I followed the instructions on https://www.home-assistant.io/addons/mosquitto/, set up an username and password, left anything else as it was and restarted Home Assistant.
Now, under Developer tools I got a new MQTT symbol where I can Publish a packet (not really sure what to do here…).
I didn’t change the configuration.yaml as the instruction said there is no need for it.
After the installation of Mosquitto Broker, I activated MQTT Service on my Shelly device, put in username, password IP address and port of the installed Mosquitto Broker following the instructions of The Hook Up (https://www.youtube.com/watch?v=VqxCf3NjVDU).
Then I added some sensors to my configuration.yaml file following the instructions on https://github.com/thehookup/shelly1tasmota/blob/master/ShellyConfig.yaml
Now, I got three new shelly sensor entities, but the sensors seem to not receive any data.
How can I check whether the Mosquitto Broker receives any data from the Shelly Sensor? How can I test whether the Mosquito Broker is set up correctly and ready to receive MQTT data?
I do not really understand the instructions on https://www.home-assistant.io/docs/mqtt/testing/.
Thanks for your help!
