Can't create new delaylight or reactor sensors

Some of my battery sensors ran out fo battery while we were on vacation

I fixed everything but the delaylight counters stoped working.

I deleted all instances, unisnstalled app (delaylight timer) adn reinstalled

When I try to create a new timer got the "Device is not ready " error and no new timers appears.

Tried installing reactor…and when tried to add a new rector sensor same error came up.

Any ideas how to fix it?

Are the devices working ok, providing updates ?
Can you wake them up when you’re trying to do what you’re doing ?
