Hi everyone, I’m diving into the world of MQTT2 and Zigbee integration with Homey, and I’m both excited and a bit puzzled. Let me share my journey so far and see if I can get some insights from the community.First off, I’ve been experimenting with MQTT2, aiming to switch from the older MQTT1 setup. I’ve followed the Homie Convention guide, setting up device topics and properties, but I’m running into some instability with device detection. For instance, when I publish a new device topic using mosquitto_pub, it sometimes shows up in Homey, but other times it just doesn’t. I’m not sure if it’s a timing issue or something wrong with my topic structure. Does anyone have tips on ensuring stable detection?On the Zigbee front, I’m trying to develop a custom driver for Third Reality devices. I’ve set up the Homey bridge and created my first app using Docker, borrowing some code from the Tuya app as a starting point. The app shows up in the Homey app, but now I’m stuck on how to test it properly. Specifically, I’m not sure how to trigger the system to interview the Zigbee device so I can debug the code. Any advice on this would be huge!Another thing I’m curious about is integrating MQTT messages to control other devices. For example, I have a buzzer that sends “PRESSED” messages, and I’d love to have that trigger a music playback command. I’ve set up some basic Switch and PlayPlaylist items, but I’m not sure how to link them so that pressing the buzzer sends the right command to the music player. Is there a straightforward way to do this in openHAB?Lastly, I’m also exploring presence detection using facial recognition with Netatmo cameras. It’s a cool idea, but I’m still tweaking the countdown logic to ensure it accurately marks people as present or away. If anyone has experience with similar setups, I’d love to hear about your configurations and any lessons learned.Overall, I’m really enjoying the flexibility of MQTT2 and Zigbee with Homey, but there are definitely some hurdles to overcome. I’d appreciate any tips, tricks, or success stories from those who’ve tackled similar projects. Let’s keep the conversation going and help each other navigate these smart home integrations!
