You are way past the point of overthinking this.
I have ever once cared how.many lamps firmware updates I ‘can do in a night’ they get done when they get done.
If I were still working in system management caring for 65000 workstations that need updates sure. But no the lights get the firmware when I get to them IF I’m solving a particular problem. You don’t redesign your zigbee network for that.
IF I’m solving a particular problem
Exactly! I’ve never understood the fascination with updating firmware. That’s one of the draws to the Zigbee network for me, it’s isolated by design, so unless a firmware update fixes a problem or brings new functionality, that I need, there is zero reason to apply it. You are just risking a change they breaks functionality or evem a bad update bricking your device.
@Sawtaytoes To see what Z2M exposes, you can go to Z2M page and see exposures for specific device. For instance for your apparent device: Inovelli VZM36 control via MQTT | Zigbee2MQTT
And don’t forget that you can use Z2M to communicate with other MQTT devices too.
I don’t think I need to convince you between ZHA and Z2M. I close the discussion at this point.
