I want to use OH for bindings/items and Node-RED for my flows/rules and HomeKit integration. I’ve installed the MQTT binding in OH and I’ve installed a broker (Mosquitto) and installed NodeRed. Now comes the hard part, trying to understand what I’m doing here xD My goal is to have everything work…

I’m operating a bit in parallel to this (though I have 0% experience with Homekit). so will see if I can help. I ended up moving all my zwave control over to HomeSeer and use the HomeSeer MQTT plugin to interface them to Node-Red (my rules engine and connections to things like Harmony and Sonos thr…

Through OH bindings for sure. I currently use sitemaps and Paper UI from OH, but I plane to use only HomeKit.

These demo videos look promising! Thanks, I’ll read it through.

Ok, that helps. How I’d suggest approaching it then, is to start on the OH side. You can either just map everything to MQTT at the event bus (be sure and define a separate publish / subscribe topic structure (I just add /set at the end of my subscribe topics for OH): http://docs.openhab.org/addon…

So far this is what I have setup for the MQTT binding. mqtt.cfg mybroker.url=tcp://localhost:1883 mqtt-eventbus.cfg broker=mybroker statePublishTopic=/myhome/state/${item} commandPublishTopic=/myhome/in/${item} stateSubscribeTopic=/myhome/out/${item} commandSubscribeTopic=/myhome/command/${i…

Let’s start with your MQTT config. Remember that publish is from OH to MQTT and subscribe is from MQTT to OH. I would suggest the following: statePublishTopic=/myhome/${item} commandPublishTopic=/myhome/${item} stateSubscribeTopic=/myhome/${item}/state commandSubscribeTopic=/myhome/${item}/set T…

OK I chaned the eventbus setup (used ‘command’ instead of ‘set’, just a preference) and restarted. Eureka, I just managed to turn on/off my switch using MQTT and NodeRED, I got here faster than I expected!! In my test flow I noticed that the buttons I used also have an input field for the topic. …

[image] piejanssens: when would one set a topic in the switch itself? If you just used a generic mqtt node you could send the topic from the inject node or from a change node in your flow. I prefer just having unique mqtt nodes for my devices. I don’t think it has any impact on overall perf…

The issue I have was related to a bug in node-red-contrib-homekit. I fixed it in https://github.com/mschm/node-red-contrib-homekit/pull/58

Fresh start, OH+Node-RED and UI = HomeKit only

While this topic doesn’t necessarily cover using an MQTT broker, it should give you some insight. There is an excellent tutorial about 3 or 4 posts down. I used it to integrate my door lock as a door lock in HomeKit rather than a light switch.
