I have ~2 dozen KLIPPBOK water sensors deployed since last November or so, right after they became available here in the U.S.
Apple HomeKit only, no IKEA hub.
I have had the "don't show connected" problem since deployment. They work if you wet a finger and put it across the contacts, and I get a HomeKit notification on my phone and iPad.
So I was glad to see yesterday a couple notices of Klippbok firmware updates, hoping it would solve this problem.
On digging around in the updates section of Apple Home, I see lots of requests for updates, and then a spinny circle. It seems to me it is very slow getting updates from the IKEA update server.
Or is this an Apple Home problem?
A penny for your thoughts.
FWIW, I am currently showing in Home:
3 Klippbok having requested the update yesterday (!).
11 having updated to 1.0.13 yesterday.
10 that updated to 1.0.11 in Nov. of 2025.
