The promise of "all available devices will be supported" gave me hope for including more Zigbee devices into to my home as Vera was not a good option for Zigbee devices.
Despite the support for new devices is extremely slow, the implementation of Zigbee has a lot to wish for and it seems a low priority at Ezlo I managed to include 22 of my 23 Zigbee devices as generic. But after 2 years of devices still missing attributes and randomly/every controller reboot loosing connection to the controller and had to be power cycled to connect again, and some even dropping off the network completely without any reason, I decided to give up.
The positive outcome of all this:
I bought a Sonoff Zigbee 3.0 USB Dongle Plus and installed Zigbee2MQTT and never been happier.
Suddenly the pairing were no pain and took a few seconds per device, all my devices were recognized, all capabilities of the devices were exposed and it never misses a signal to/from a device ever.
I'm surprised how stable and configurable my new setup is. I can set device parameters, offsets, send messages handled by the bulbs them self like effects, broadcast for groups, transition time for power on/off. I can handle debounce for MQTT messages, do OTA firmware update on devices and much more! Most of this is probably standard for the common branded hubs like Hue etc but I never had one so this is new to me.
A big plus for me is the MQTT part of Zigbee2MQTT as I'm migrating as much as possible to MQTT.
My Ezlo Plus is now serving as a modified WiFi access point to my network and only have the VistaCam 1203 Doorbell still connected for evaluation. Time will tell if I ever move my Z-wave devices to it.
Conclusion:
I could really recommend both the Sonoff 3.0 USB Dongle Plus and Zigbee2MQTT to anyone going the same path!
