I’m trying to add new Click On Click Off (Klik Aan Klik Uit) door sensors (AMST-606), but there’s no response from Homey. Existing door sensors also stopped working. - I’ve tried different sets of AMST-606 - I’ve tried pulling the plug on Homey and restarting again - I’ve added other COCO / KAKU switches (wall plugs) with success - I’ve checked the battery and hear a clicking sound in the sensors Any ideas how to remedy this? ---

Plz some more info on FW and app version. > [@Davied](#): > > I’ve checked the battery Did u measure the battery? Because that’s the only good way to “check” a battery. Did u also measure the battery’s of all the rest of the 433 devices? When one has a low battery they are gonna shout at the 433 band and block the rest of the traffic. ---

I also have a number of COCO/KAKU wall plugs. They work fine. Wouldn’t they be blocked out as well? 🤔 ---

I have exact the same problem, I’ve got 3 door sensors, 2 have stopped working. New batteries, reset, ptp, app uninstall, installed stable and Beta Kaku app, nothing worked. I’m waiting for 2.0 now ---

Excuus, @Rocodamelshekima, ik zie nu pas je bovenste vraag. Versie KAKU-app: 4.0.14 Versie Homey: 1.5.13 FW = firewall? Wat wil je daarover weten? ---

> [@Davied](#): > > FW = firewall? Nope. FW=FirmWare version of ur Homey. And because we are in the English part of the forum it would be nice if we keep it in English 😉 ---

Good for you! I have 1.5.13 for two weeks now so that´s not my problem apparently … ---
