I'm on the way from Vera to Hubitat. Here is my interim report with first experiences. Maybe it's helpful for someone.
My Vera system has grown up since 2015: 60 z-wave nodes (mostly multi-devices), about 30 virtual devices, 35 scenes, many GET integrations and 2000 Lines of LUA code.
My reached Level on Hubitat after the first month:
40 zwave-devices successfully moved (min. one exemplar of any device type). Mostly with more functionality than before.
Aeon DSD31, Aeontec Siren ZW164, Aeontec NanoSwitch, Aeontec SmartSwitch7 ZW175
Fibaro Smart Implant FGBS222
Nodon Soft Remote
Philio Siren PSE02, Philio Relais PAN04-1B, Philio Relais PAN06-1B, Philio 4in1 sensor (motion, door,...) PST02, Philio Plug PAN16-1
Popp/Danfoss POPE010101 TRV
Qubino Relais/sensor ZMNHAD1, Qubino Relais ZMNHND1, Qubino Relais ZMNHBD1
Remotec Button Controller ZRC90
Vision Door sensor ZD2102
Aeontec Multisensor ZW100 tested but removed for the moment because of excessive notifications.
Philio 4in1 sensor PAT02 (flood, humidity, temp) not completely running.
First tests finished (virtual devices, variables, rules, dashboards, button controllers, ..) and first rules running.
Draft finished transferring the functionality (configuration and object names concept).
I expect the standard functions of Hubitat (incl. some community driver and apps) are enough for me: Rule Machine, Maker Api, Dashboard, Groups. Button Controller, variables, virt. devices. No more coding necessary. There are much more options, I do not need and discover at the moment.
First impressions and experiences (system handling, development speed, ...).
Including devices and setting configurations is much, much faster than with Vera.
It's hard to get the first understanding of the diverse logical structures. There are many options and it's time-consuming to understand their advantages, limits, dependencies. The documentation is not very helpful for this. I needed many tests and many searches in the community forum.
The configurations in the Rule Machine are nearly self-documenting. The log and debug options are good. Unfortunately, there is no complete email functionality.
