Zwave Doorlocks, one is zwave plus and struggles

I have 3 Doorlocks with Zwave cards.
I upgraded 1 lock to zwave plus card thinking it would be better.

The zwave plus lock is actually close to my zwave stick. And has 3X zwave switches right next to it

It must go to sleep or something and home assistant looses it. I can pull the batteries and reinstall and it will wake up

Any thoughts on keeping it awake?

It has been lost for weeks at a time.
