same “issue” here. Using only Sonoff devices incl. USB 3 stick on RPi4b running HA 2026.3.4.
another user describes the exactly same situation here:
Hi all,
Very new here, been using Hubitat for a couple of years but have recently started tinkering with HA. I have recently paired a zigbee Centralite Pearl thermostat using a Coordinator about 5 metres away. I also paired a Sonoff plug at about the same distance. After a few hours the thermostat becomes unresponsive with the error in the Subject line; when I look at the zigbee map it does not show offline.

Can anyone provide some troubleshooting tips? I have seen that if I pop the …

### The problem
I seem to be having a problem with battery powered valves and Z… HA. When trying to switch the valve on/off I receive the following error:
Failed to perform the action switch/turn_off. Failed to send request: Failed to send request: <Status.NWK_NO_ROUTE: 205>
This happens on:
- Aqara T1 Valve Controller: lumi.valve.agl001
- Sonoff Smart Water Valve: SWV (though it seems to work sometimes with some delay)
I use a Sonoff Zigbee 3.0 USB Dongle Plus through ZHA. After multiple retries of setting the whole network up from scratch, replacing batteries and removing and readopting the devices, I don't know how to continue. What next steps can be taken?
Status updates when manually switching on the device are being send back to HA. So it looks almost like the device goes to sleep, dropping connection from the Zigbee network.

Has anyone found a real solution or do you think this is a ZBHA integration problem in general since it seems to brake very often especially “around” updates?
