Add an attribute with the "Last Activity At" Value

[axornet]

First, Thank you!!! The integration is great, Hubitat is great at adding Zwave/Zigbee devices, HA is great in the other areas!
I do not know if the correct place to ask for a feature.

Could we add in the status of the devices the "Hubitat Last Activity At". This is my use case.
I have NodeRed flow in HA, that validate the battery level of the devices and informs me, but sometimes the battery is no more updated and stays at a fixed value because the devices stopped working and are not reporting anymore to Hubitat/HA

Today I have a motion sensor at 37% battery reporting to habitat, but the last Activity is from March (today is June), the battery never reaches the level of 30%, the threshold I set to inform me.

Thanks!!

Adding more info:

I checked the result of the maker API and for this particular sensor, the date that is separated below is the one I am looking to have.

{"name":"Generic Zigbee Moisture Sensor",
"label":"Water Leak Master Bath",
"type":"Generic Zigbee Moisture Sensor",
"id":"1140",

"date":"2021-03-04T17:52:15+0000",

"model":null,
"manufacturer":null,
"capabilities":["WaterSensor","Configuration","Refresh","Battery","TemperatureMeasurement","Sensor"],
"attributes":{"water":"dry","dataType":"NUMBER","values":null,"battery":"37","temperature":"72.92"}

Thank you
