This was my first major Zigbee mistake, using channel 26 since it was the one with the least WiFi interference. I struggled keeping pretty much every Ikea device connected since Ikea apparently doesn’t support channel 26 very well.
The “most compatible” Zigbee channels are 11, 15, 20, or 25. 11 has pretty significant WiFi interference so try sticking to 15,20 or 25. These are known as Zigbee Light Link channels which are intended for OTC consumer lighting applications. Minimizing interference takes a little planning. You need to look at what you can control (essentially your Zigbee channel and your WiFi channel) as well as things you can’t control (your neighbours WiFi channels for example).
You could try plugging it in and seeing if it just works, but 5 minutes of checking WiFi congestion around you and selecting the best channel based on that can save you hours of headaches in the future. Remember, if you change your channels after you need to go around and re-pair all the devices, so you may as well do it while you’ve got a clean slate.
