I have a Cync Bluetooth Light I would like to set up in Home Assistant but unfortunately the only integration that works with Cync lights is this one:
But I don’t have a wifi bulb or switch, so it doesn’t work with my bluetooth mesh bulb. I would really like to find a way to use cync2mqtt in Home Assistant but I can’t figure out how. Can someone make an add-on for it? Or is there another way? I’m running HA OS.
Thank you!
you ever get this working?
Hi - Just a followup on this. I wrote the cync2mqtt script - and use it pretty much only with HomeAsssistant all the time (the MQTT topics should get auto discovered). It should support all the older CYNC bulbs and switches. The easiest way (I think) to get it to work is by installing Raspberry PI OS on a Raspberry PI Zero-W or 2W and running it on that. At some point - I had considered trying to create an enhancement branch of cync_lights to add the cync BTLE mesh support for HA directly (which would have the BIG advantage of allowing ESPHome BT bridging). But at this point - I don’t think it’s worth the effort - since all the newer Cync direct connect bulbs support Matter over wifi - and that hopefully all natively works in Home Assistant now.
You’re right, the main HA integration doesn’t cover Bluetooth-only Cync bulbs. I’ve looked into cync2mqtt too, and it looks promising as a bridge, but it’s still pretty early-stage and not packaged for easy use with HA OS yet.
Since you’re on HA OS, running cync2mqtt as a custom add-on would require wrapping it in a Docker container and making sure it has access to your Bluetooth adapter, not super simple, but possible. Alternatively, if you have another Linux machine or even a Pi with Bluetooth, you could run cync2mqtt there and just point HA to the MQTT broker it’s using.
It might be worth opening an issue on that GitHub repo or the HA forums to see if anyone’s already working on a containerized version for HA OS. Would love to see more support for these bulbs, too.
