Battery: I think most Chinese suppliers put the 2032 battery in. Hence the lose connection. Like you stated: The CR2450 type supposedly is the correct type which is more expensive and therefore not supplied at all times. I did not check but I suppose, it's not only about more capacity but also thicker.

I did buy some 2450s but think they were physically too big for it in the end.

In my HA I can add the device but it does not respond with open and closed iaszone status. I have two and neither work, while contact sensors from other manufaturers are fine

I had issues where it just stopped responding. I could add it and then it would never show as open/closed. I ended up replacing my Sonoff with Aqara which have been reliable.

Shame you missed out the step showing how to put the device into pairing mode.

Apologies, because it was an unbox it was in pairing mode straight out the box. There is a small reset pin (like mobiles) that you can press & hold to reset

the bloody thing doesn't work for me. ZHA does not find it. what am i doing wrong?

Not sure why ZHA doesn't find it. Are you close to the hub/USB stick? Do you have powered devices extending your zigbee network?

i ran into the same issue. when you pull the hardware out of the case, you can find at the battery side a small button which could be used to start the pairing process. this worked in my case

@@JoeyPat83 You can access that button via a small hole in the case too. Press for 5 seconds to put it into pairing mode. There's an LED visible through the case that should flash 3 times to confirm.

Compared to the aqara ones these are ultra garbage.. battery life is really bad

I do prefer my Aqara sensors. I have found them more reliable than the Sonoff.
