Not sure if this is possible.
I have used OHM for a number of years and was elated to see a component for HA. Thanks for your hard work on this.
I monitor two computers that are not always on. I have found that the OHM sensors won’t initialize unless the computer is on (obviously) but don’t initialize when a computer is turned on after the sensor has made its initial observation that the OHM instance is unavailable.
Is it possible to tie a device trackers state to the OHM sensor? If the associated device tracker comes “home” in HA then the sensor starts. If the device tracker changes to not_home the sensor would stop looking for updates until the device is home again.
