Feature request - A notification sent (email, text, whatever) when an ESP Controller is not seen for X amount of time

I recently had a problem with fermenting temps during a power outage on my controller. Thus, the ESP8266 controllers weren't powered up and did not communicate back to the Fermentrack software on the Raspberry Pi. My beer temps rose in the summer heat.

If the Fermentrack software would have a timer when the controllers were in the state of "Cannot receive LCD text from Controller/Script" for a certain set number of minutes and then emailed or texted or somehow alerted me that there was a problem, I could have caught it sooner. It would have to be a notification sent much wider than the home network, since being away from home for extended periods of time with no temp control can be catastrophic. But if I'm home, I may just notice it anyway. But either way, should be able to be sent regardless of the destination. Heck, even a recorded message phone call from Fermentrack. Anything.

Thanks.

I like it. For (reasons John doesn't want to hear anymore) I could use this.

You can write a bash script to parse the end of the device log. If it stops changing, trigger a push to telegram. Adding onto that, if the temp is null (temp probe issue) or temp is out of range (fridge open) trigger the alert.
