Lighting controlled by home-assistant is endlessly frustrating. Especially if zwave. The networks are slow, the devices are awkward to configure, and when things go wrong debugging is difficult. Sometimes it takes my lights a good 60 seconds to respond during which time I'll try a few different button dances which all then get lifo queued... End result is light automation that works 95% of the time with the 5% remainder being enough to sour the whole experience.
This isn't home-assistant's "fault," it's the zwave product space being a convoluted mess that HA tries to paper over. Other integrations are better but each integration is a separate plugin thing so quality depends on who wrote the plugin.
My house got a 10% premium due to the home-assistant setup according to the realtor. Lights and music and blinds all easily controlled from an iPad mounted to a thing in the hall. I left all the equipment including the raspberry pi that ran HA, but I took the SD card for privacy reasons. 99% certainty that they don't even know what Z-wave is let alone how to rebuild the network... I'm sure that if I buy a "smart house" in the future it will be beyond my abilities.
