I am a longtime Vera user, over 10 years. I switched to Hubitat last March and have been very happy with my decision.
- Hubitat is well supported. They do a code drop every few days with new devices, bug fixes and roadmap changes
- Hubitat has an very active user community and strong forum to seek advice and help.
- Hubitat support thousands of device.
- The platform is stable. I have only had to reboot my unit once in 9 months. I have since put a wifi plug switch in front of Hubitat so I can power cycle it remotely if need ever arise.
- Rules are different than Vera scenes but very powerful. There is a bit of a learning curve to transition from Vera to Hubitat but you can start small and take on more and more as you get more comfortable.
- The UI process for Hubitat is a weak point. Its slightly better with the new UI capability but it seems circa 1990's in capability. If you want to learn css you can customize to your hearts content but that is a steep learning curve and only for code warriors.
- I haven't found a good 3rd party iPhone app to dashboard Hubitat. Hubitat has one but it is the same UI and mundane unless you get deep into css. I loved Homewave for Vera but I don't see an equivalent to Hubitat.
- While I mostly use ZWave Hubitat support Zigbee and Matter. I haven't tried these yet but will wade in eventually.
- Hubitat can get confused on complex rules that turn on lots of devices in a single rule (like an "all on" or "all off" rule. It works 90% of the time ok but 10% of the time I have to run he rule a second time to clean up devices that didn't update. Interestingly most of the devices that didn't update (about 80%) actually changed to the proper state but just never had the device or GUI reflect the new and proper state. A device refresh fixes this. So I have a "refresh all" rule as well.
- Conditions in rules allow conditional execution of actions. Here you can trigger on an event but then only execute the action if a condition is true. For instance trigger on a door opening but turn on lights only if it is dark outside.
Anyway I had given up on Vera and Ezlo due to he slow progress on the platform. Ezlo is very buggy, changes are glacial, and many features are only partially implemented as if they were a demo for a proof of concept meeting. Not hardened as needed for an important home control appliance. They do a lot of apologizing on the Ezlo forums but not enough action behind it.
