Zigbee pairing of Chinese "no brand" devices

Hi all

I am having problems pairing these buttons:

Following the pairing procedure they seem to not be detected. Any idea how I can check the logs for Deconz to see if they are actually broadcasting and just not supported?

Update:

I have deduced that this is one of them:

Looks to be a TS0218, which is listed as supported

but does not work.

I know this a bit of an older post, but did you ever get this working? I got one, HA finds it, but button pressing does nothing.
