Offline detection for Z2M devices with last_seen

Thanks for your reply. All inputs except of 3 are ok - but that’s the reason for that blueprint. I’m sure there is a new requirement for code with unknown input. The code needs a default set like this “default=0” - but i can’t find the right place. The error message directed to “as_timestamp”. Any thoughts about that? Thanks

Ok - really strange! I changed nothing, but after a few days it just works.

Thanks anyway!

Many thanks for the code.

I have slightly adapted the code by adding two functions: “Minutes not seen” and “Included Sensors”.

Regards!

Hello, I am out of ideas, please (and sorry if I post to wrong site). When I use this bueprint, I recieve this message: “Last seen (unawailable) Last seen (unawailable)”. Alld evices are awailable, so where does this mesage come from ? why it is generated?

This is great, thanks. Would it be possible to add Notification Channels for Android devices?
