Hei! I’ve been away for some weeks. before leaving I pulled the plug on some connected electronics taking some of my zigbee power sockets (which function as routers) off-line. In the developer tools I see that the Routs are unknown. Hitting the refresh button gives a “Network request failed” message (in the bottom left corner of the page - see screenshot). Questions: - Is there a way to re-establish the zigbee network? (wasn’t this a Homey firmware v5 feature?) - Any ideas to what the “Network request failed” is hinting to? - Any chance of the nodes becoming active again over time? Any help addressing the issues is much appreciated! ![Skjermbilde 2021-07-31 kl. 23.01.49](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/e/a/ea844e5d85265c1f3d8a3306c8393de3f59b2861.png) ---

“Interview” the router devices might do the trick. Zigbee ‘should’ rebuild itself. If it doesn’t, maybe re-pairing does the trick: > [@Fixing disconnected Zigbee devices (without having to modify all flows)](https://community.homey.app/t/fixing-disconnected-zigbee-devices-without-having-to-modify-all-flows/37896): > > With the release of Homey firmware 5.0.0 some improvements have been made to the Zigbee stack. I experienced some devices that stopped communicating with Homey in previous firmware rc’s. For me most where battery powered Aqara & Xiaomi ZigBee sensors As I didn’t want to have to fix flows I have do the following: Remove the battery for a couple of seconds And/Or start pairing the same device without removing it, just in place where it was mounted. (Not near Homey) you get a [dupicate de… Oh, from what I experienced “Network request failed” means “Homey was very busy for a while, try again” ---

Thanks for the reply! On question to better understand how Zigbee works: Is it so that when I add a router capable device, the other devices will over time adjust and find the optimal route including the newly added router? I do not need to trigger this in any way? ---

YW! True, the zigbee mesh is dynamic and not managable. Aqara sensors seem to stick to their original router device (Homey controller itself or a router device), so when it tends to “fall off” the mesh, consider re-pairing them at their final location. [Athom’s zigbee wiki](https://homey.app/nl-nl/wiki/wat-is-zigbee/) Keep in mind, your (or neighbour’s) wifi can interfere with your zigbee network(s).
