Sonoff ZBMINIL2 reliability

I’m not sure if this is due to deCONZ (2.24.1 beta) or the Sonoff ZBMINIL2 hardware but I have 24 ZBMINIL2’s hooked up to all the light switches in my house and at any given time there are at least 3-5 lights not responding to Phoscon commands and won’t toggle on/off.

Sometimes if a toggle the switch manually the status is updated in deCONZ/ Phoscon and therefore I know it’s connected but I am unable to toggle the same light using Phoscon or the REST API.

Are there any steps I can take to troubleshoot the issue?

Can you share some logs ?

Here you go 10:40:07:103 asdu: 180f01000000100010:40:07:103 APS-DATA.indication from chil -

Looks like you have interference issues:

  1. 10:40:12:966 0x0017880104651E1E error APSDE-DATA.confirm: 0xE1 on task
  2. 10:40:22:587 Poll APS confirm 221 status: 0xE1

Are you using an extension cable?

Yes, I’m using a USB 2 extention cable

Other than that, check Wifi channels, other USB ports around and general USB3 signal noise.

Thanks for the help

I’ve done some troubleshooting and moved the computer running deCONZ to a new location and ensured my Conbee II at the end of a USB 2 extension cable isn’t near any other electronics but I’m having the same issue. All my devices work at first and then within a couple hours my system loses connection with some of my Sonoff ZBMINIL2. I don’t think it’s a signal / interference issue as some of the ZBMINIL2’s that are not responding are in the same room as hue light bulbs that are repeating the signal. I have about 20 zigbee light bulbs, 6 outlets/ plugs and 4 Hue dimmers that are all working perfectly. The problem seems to be isolated to the Sonoff ZBMINIL2 hardware.
