Monitoring Home Assistant - How are you doing it?

This worked brilliantly for a few weeks but now ‘my’ emails to ‘myself’ are bouncing for some reason. Anyone else seeing this?

I’m using hassIO which has a built in watchdog, it restarts HA automatically if it goes down.

I also have it publishing MQTT messages once per minute, and NodeRED reads these messages and sends me an e-mail if it doesn’t get a message for 10 minutes.

EDIT: That uptime robot link isn’t working, for me, does it work for anyone else?

Wondering if this might fix the Google Sheets/Scripts problem. Trying it

Nope. It breaks email notifications totally.
