[BUG] Battery operated devices appears as "unavailable after some time

Environment

• ShellyForHASS release with the issue: 0.1.9
• Last working ShellyForHASS release (if known): I guess ~ 0.1.6
• Home Assistant Core release with the issue: 0.112 - 0.113
• Operating environment (Home Assistant/Supervised/Docker/venv): HASSIO - Home Assistant

Describe the bug

Sometimes it happens, that one or multiple Door / Window Sensors appear as “unavailable”. When i check the details, one sensor change the status from “Closed” to “Unavailabe” 10 hours ago, another one 3 hours ago. I never saw this before, only when the batteries are empty and the device is dead. If i force the sensor waking up (e.g. open / closed the window/door) than its “alive” again. This happens not only for specific sensors, it happens randomly for mostly every of my D/W sensor at no specific time

Steps to Reproduce

Unfortunately there is no way to reproduce, it simply happens randomly

Expected behavior

It should stay with the last status. Maybe only mark them as “unavailable” when it doesn’t update for over 72 hours

I had overlooked one very useful feature in the Shelly DW2. This was disabled by default:

I enabled it, and ever since my Shelly DW2 has been waking up throughout the day to report illuminance and temperature values. This is the illuminance history:

I’m very happy with these results, hopefully it will last.

As for the Shelly Motion, it has a bug that causes it to never wake up from low power mode if it doesn’t detect any motion for a long time. It has been reported and the devs are working on it: https://www.shelly-support.eu/forum/index.php?thread/8921-device-is-offline/ https://www.shelly-support.eu/forum/index.php?thread/8905-wifi-re-connect/

No, actually I’m the one still learning things: I was oblivious to that setting in the Shellys! Thanks for the share, and I again hope you can figure it out.
