alarmdotcom VS SonoffLAN

It looks like there is a custom HA integration for these, but it relies on webscraping as alarm.com don't provide any API or local control options. So it's an option but do take note of the caveats listed in the description. https://github.com/pyalarmdotcom/alarmdotcom

If you're stuck on the Sonoff Micro as you seem to be (they are pretty cool and cheap as chips so I get it) it runs off the eWeLink app but there's a Sonoff add-on for Home Assistant in HACS here https://github.com/AlexxIT/SonoffLAN that makes it work locally, but it does need to be added via the app first.

This is the HACS available integration with HA that I'm using: https://github.com/AlexxIT/SonoffLAN

You plug it in and set it up to go on/off whenever you want. That model comes with monitoring aka it can see how much current is going through it. Then you use something like https://github.com/AlexxIT/SonoffLAN with Home Assistant and setup a specific automation. e.g. if watts usage is > X, then do Y. yadda yadda.

I can recommend these together with the sonoff zigbee bridge using the custom integration sonoffLAN https://github.com/AlexxIT/SonoffLAN.

And for the node-red direct connection, I haven't tried that. I use AlexIT's SonoffLAN to connect between my Sonoff Basics and Minis to HassOS without connecting to the cloud.

Using this thing https://github.com/AlexxIT/SonoffLAN I got it all working without tasmota! Well except that currently the zibgee bulb is only on/off but perhaps that can be sorted. So no need to flash anything in order to try it out at least.
