Found a way to fix this. Seeing @Caseda’s comment on the old forum.
First set motion to “no” and save settings (push black button and then press save within a few seconds). Then set motion to “yes” and save the settings again. After that it will work (at least for me). I also set the raw parameter “5,1,2”, but that shouldn’t be needed.
currently the whole app is not working, i installed the beta app and since the last beta app update the app constantly crashes which makes the sensor complete useless.
I cannot change any setting etc, the whole sensor icon is greyed out in devices…
Also it seems impossible to install the stable version over the beta version, to do that i have to completely remove the app and install it again, doing that all flows brake which use the sensor…
don’t know, i disabled the app, it kept crashing and nothing worked anymore.
The crash log was send to athom.
Sadly just enable and disable the app is not the solution, the app only disables when you reboot homey. So when it keeps crashing and you disable the app it keeps reporting it crashed until you reboot homey, after reboot the app is really disabled and does not send and reports any crashes anymore.
So i do not enable it only to look for a log…
I wait until athom fixes the problem, i hope it will be shortly…
Problem is solved last week, download latest beta app from store.
I send my gen1 sensor to athom, they used it to fix the problem and can confirm the fix works now.
Motion detection is finally working again on 4on1 multisensor gen1
