Monitor Health Status of Bosch Motion Sensor

I have two Bosch pet friendly motion sensors using the DTH from Tomas Axerot (thanks Tomas). These generally work well.
However, if they go offline for any reason (eg the hub, SmartThings V2, reboots) then they will not come back online automatically like the rest of my sensors (a mix of Samsung and Aeotec). To get them back online I have to remove the batteries, wait a few seconds and then replace them.
Is there any change I can make so they will reconnect?
If not, is there a way to send a notification to tell me they are offline?
