I’ve been happy with my setup for two years, I’ve got 15 devices, ikea light bulbs, ikea switches and motion sensors, it all works perfectly until last month or two.

Motion sensors start to change the status to “clear” which triggers the lights off while I’m still moving in the kitchen and bathroom.

Quite often now lags happen between motion sensor switching on the lights or the switch turning lights on or off - it always used to be instant.

My setup is not the newest as I’ve got RaspberryPi with CC2531 but I’ve been running old software all that time so that’s not the case, I’ve only updated everyone now hoping it will fix my issues but that didn’t help…

I know probably you will say I need to check logs but did anyone experience this?

I don’t use my setup for anything else like Plex Server or FTP etc…

That’s some examples errors I found when I was using ikea switch to turn the lights on.

Is it best to have HA on Windows instead using different dongle like SkyConnect?

Update: Thanks to @[email protected] for pointing me in the right direction. Somehow I never considered interference to be an issue. Recently I bought a Google Wi-Fi mesh system (pack of three) and I didn’t realise it could have caused interference with zigbee… I changed the channel from the default 11 to 25 and the whole setup is working perfectly again! I also moved the RPi closer to most of the smart devices and I’ve put the USB coordinator on an extension cable but I’m 99% sure the channel 11 was the main issue.

    I’ve definitely not experienced this and I use a CC2531-based network in a very large home with about 40 zigbee devices. My setup was originally deployed for Zigbee a few years ago and has been pretty reliable. A quick Googlin’ indicates that the MAC access error can be caused by WiFi interference though. Have you tried changing the zigbee channel?

    EDIT: Meant to include the link to the zigbee docs about the Mac access error you’re seeing. https://www.zigbee2mqtt.io/guide/faq/#common-error-codes

      I second this. 2 updates ago I got a repair warning stating my Zigbee and Matter were using different channels. During that time I noticed delays with my devices. As soon as I put them on the same channel I noticed an immediate improvement. But I am using Skyconnect as multi-protocol so this may differ from OPs setup.

      This might be it actually, I’ve bought google Wi-Fi mesh with three access points about a month ago, two of them are running in ethernet backhaul mode but one is not, I wouldn’t be surprised if this was causing interference…

      Thanks for this, I’ll look into it.

      Many thanks for the suggestion, I changed the channel from 11 to 25 and it’s working perfectly again!
