What really drives me nuts is that I regularly loose devices from the network, for example the Aqara pushbuttons. I understand that the network needs hubs to guarantee connectivity in remote areas. I have a number of TradFri Zigbee bulbs that act as hubs.
What I don’t understand is why a device should be lost permanently when temporarily a hub becomes unavailable (for example, if I unplug a lamp). In a robust network I would expect the device message to be re-routed through other hubs, or at least re-establish a connection when the hub becomes available again later. With my Aqara buttons, this seems not the be the case. I need to re-pair them, only to find that a while later they are lost from the network again. Sometimes “a while” is a few hours, sometimes it is many months.
Why is this happening? Doesn’t a Zigbee network provide this form of robustness?
If it is an Aqara-only issue (and no, I don’t plan to get their hub), what are reliable Zigbee buttons that work with ZHA?
Which was handy when replacing v1 with v3 devices as I could use the existing bases that were extremely well stuck with the supplied double sided tape. That stuff is difficult to remove even with orange oil and alcohol. I was disappointed in myself that it took me about half a dozen replacements before I realised I could do this.
Apart from the very occasional drop out, my 1.2 devices seem to do ok, so I suspect I’ll keep hold of them until I have a more compelling reason to upgrade them.
