**BLUF** : 7 of my 8 UK Fibaro Wall Plugs (only the FGWPG-121 version) have gone stale on power/energy reporting, some for weeks. Turns out they’re all running under `com.fibaro:FGWPB-121` — that’s a US driver?, on UK hardware. Not sure it’s the cause but seemed too weird not to mention. One older FGWPG-111 (no USB) on the same Homey has never missed a beat. **Setup** : Homey Pro, 7x FGWPG-121, all correctly S2, params 11/13/14 set properly (checked more than once). Along with lots of other devices working fine, network health is good; distances and hops vary. But power/energy data just… stops. Devices still respond to on/off fine, it’s only the reporting that dies, along with not able to push updates (unless powered on/off, but still no data) Checked the driver via tools.developer.homey.app/tools/devices out of curiosity and every single -121 shows `FGWPB-121` — the US type B one (UK is G?). Even a freshly re-paired unit uses this driver, so it’s not some stuck historic thing . Don’t think this is the cause though — but still feels like it might be related? Bigger suspect imo: these -121 plugs use multi-channel i think (1 channel for the mains socket, another for the usb), the working FGWPG-111 doesn’t use multi-channel at all, reports meter straight at root, could that be related? (i tried to trick it into using 111 driver, no joy) There’s an old thread here ([link](https://community.homey.app/t/power-and-energy-are-not-updated-qubino-and-fibaro/47940)) where folks called it “a minor app bug” for a near-identical Qubino/Fibaro symptom, and a couple of people there said excluding+re-adding temporarily fixed it (mine just did too, watching to see if it holds). but that’s not practical really. 1. Anyone else on a UK -121 want to check their driver and see if you’re also showing FGWPB-121? 2. anyone else seeing same issue with these 121 plugs ie stale power values 3. anyone else had this and fixed? 4. any other plug that actually works? ---

Why? The app is made by Athom. ---

Seen similar on none homey platforms too, figured worth a try
