Same experience here. Support is getting worse, things are getting more buggy, and many “supported” devices actually don’t do anything useful.
There seems to be no quality control for the apps created by the community, resulting in weird apps that don’t actually do anything (such as smart thermostat’s we can make dumb so homey can make them smart again). Configuring and managing things keeps getting harder and harder.
Bought a nanoleaf… -> a week later support by homey disappeared.
Xiaomi sensors are getting worse as well. Very often after switching off they will not switch on anymore, leaving me in a dark place while doing my business.
Same goes for some of the smart led bulbs combined in a Virtual device: Very often when I turn off the lights at home (still have to do this with the app because homey just doesn’t want to play nice with some of the sensors I have installed) one of the bulbs in the group will just turn itself on again and again, and I have to walk over to the light switch as a caveman to turn it off.
Another great example is the generic philips TV remote app: Impossible to set the channel, as the button mappings are completely wrong. I can turn off and on, but simply selecting the hdmi2 channel sends me to the USB folder structure, while the USB channel sends me to live TV.
To be honest, I am currently setting up a RSPI with Domoticz, and homey is going to be degraded to a really expensive paperweight. It’s sad it has to come to the situation where Homey can be replaced by a €35 Rspi with about and some additional hardware.
I can only say that if you are not able to set up your own domoticz device you will probably not be able to get and keep homey running. This is what I think the major issue is. Homey is being sold as the complete solution for all home automation, while people actually need to be quitte highly skilled to keep things running. I’m just very happy I didn’t connect my home security to homey yet
TLDR: Frustrated user gave up. Will not be using homey anymore.
