I’ve been steadily increasing my Z2M network and I now have around 48 devices; Aqara wireless sensors, a couple of Hue light bulbs and some Ikea bulbs - so a good mix of battery and powered devices.
I have recently changed the firmware of my CC2531 USB stick to the source_routing firmware as that is supposed to support more devices.
My USB stick is connected to an extension cable and put away from the server.
I have paired a couple devices directly with the USB stick (mostly powered ones), other devices I have paired to the light bulbs.
In other words, I think I have done all the recommended steps to have good throughput, but still I find that I’m losing devices every day. I don’t have concrete evidence, but it feels like every time I fix a device by re-pairing it, another device randomly drops off - in other words, it seems like there is an upper limit of around 45 devices.
Is there anything else I can do to make this more stable? I didn’t start over after updating the firmware; should I delete the whole database and start over to make sure the linkages are correct?
I have attached a screen shot of my Device Map. It seems a bunch of devices are not connected, but they typically work fine.
