Motion detector no longer reachable

kukrapok — Mon, 04 Aug 2025 09:21:23 GMT

Hello,

few weeks ago (can't say if it's related to 10.28/10.29 updates or not, but that's when I noticed it), my Motion detector is no longer reachable by the Android app. The device was at this time flashing red (once every .. minute?), reported on the Android app as "cannot be reached". The batteries are OK and the device is in range.

I tried to delete it/re-add it, but I get:

Error

It was not possible to access the network

Since it's no longer possible to delete it, I tried to reset it -> now it's flashing orange every 10sec then red. Another reset attempt led it to be flashing orange indifinitely.

This not-reachable status is exactly what I get from another device at https://community.bosch-smarthome.com/t5/funktionen-und-nutzung/universal-switch-ii-compatibility-with-controler/m-p/93767#M25035, maybe for other reasons, but I wonder if the cause is not at firmware now.

The controller (v1) has been changed meanwhile, but I still face the same issue with the motion detector.

Any clue or hint?

@kukrapok it seems that we could reset was not correct. Here you will find the correct steps for the reset.

I followed the reset procedure described here: https://www.youtube.com/watch?v=rEgb-Jv0C8M
I got the exact same LED color sequence, but at the end, it's flashing orange every 10 sec.

@kukrapok that shows that the is not connected to the controller. If Zoe seething a device, you have to delete it in the BSH app as well. Otherwise you can not connect it again.

OK. Excepted that.. the app cannot delete a device when it cannot communicate with it. Not well-designed :-/.

@kukrapok that would not make any sense. Otherwise a device will bei automatically deleted, if i.e. 🔋 are empty.

Of course it does not make any sense, that's why I say it's badly designed (and buggy).

Here is what I get when I try to remove a device when the app is not able to communicate with it (same case in the other forum post I mentioned in the first post here):

Error

It was not possible to access the network.

@kukrapok Your smartdevice and the Controller need to be the same network.

How could they be on different networks? What networks are you talking about?
