Home Automation Guy on YouTube has a great video about some steps you can take to build a reliable Zigbee network! https://youtu.be/t-gw7kURXCk
@andy_warb @zigbee @homeassistant #HomeAssistant
My rules for setting up #zigbee & #Zwave meshes:
1. Put the dongle on an extension cable and place it at least 2m away from the rPi, especially if you have a plastic case
2. Start pairing with the closest mains-powered device and work your way outward
3. Only after all mains devices are in the mesh do you add battery ones. Add them where you're going to use them, not near the coordinator.
@andy_warb @zigbee @homeassistant
And if you're doing initial setup of a #ZigBee mesh, pick a channel, don't let it pick one automagically.
You want to make sure it doesn't overlap with your 2.4GHz wifi - see https://www.metageek.com/training/resources/zigbee-wifi-coexistence.html for details

@andy_warb @zigbee @homeassistant my Phillips hue hub seems to *insist* on being on the same channel as my AP
@schizanon @andy_warb @zigbee @homeassistant
It's much easier to change the WIFI channel than the #ZigBee one.
Hopefully I'm understanding it wrong, but changing the ZigBee channel requires you to reconfigure the radio dongle, then re-add every single zigbee device.
@unixorn
@andy_warb @zigbee @homeassistant yes, but Phillips Hue seems to follow the wifi for some reason.
@schizanon @andy_warb @zigbee @homeassistant
I'm surprised the Hue can move channels, I thought that #ZigBee was locked onto a channel once you configure the coordinator.
@schizanon @andy_warb @zigbee @homeassistant
How many wifi networks can you see at your home? Maybe there are enough other SSIDs on the other channels that whatever your WIFI is using actually has less interference and the Hue is picking it because of that.
When I was living in townhouses and apartments I could usually see over a dozen SSIDs, so there were no clear channels, just less awful ones.
@unixorn @schizanon @andy_warb @zigbee @homeassistant it shouldn't be able to move channels - I changed my WiFi channel because of the hassle of reconfiguring the ZigBee network, then re-pairing everything.
@unixorn @andy_warb @zigbee @homeassistant Does this help when the HA automation using motion sensor and light is slow?
@sstranger @unixorn @zigbee @homeassistant quite likely! Also if you’re having trouble with devices losing their connection.
@sstranger @andy_warb @zigbee @homeassistant
I haven't had speed issues with my sensors. I moved my zigbee from a huzbsb-1 to a conbee II so that I could run #zigbee2mqtt on a different HC2 than the one I run #zwavejs on. I run HA on a 3rd since I have several odroids I'm using as #moosefs chunkservers and don't need to jam them all into one machine.
A stronger mesh is always a good thing though.
@unixorn @andy_warb @zigbee @homeassistant I'd also add, that if you are using software that allows you to, turn on permit joining on the mains powered router that is closest to the battery powered device. A lot of cheaper Zigbee devices (eg my Aqara temperature sensors) - simply do nothing if you tell Zigbee2MQTT to permit join on all devices, I think because it's trying to reach the coordinator directly.
Only turning on Permit Join on the closest mains router though, and it joined in seconds.
