EV charge controllers Mainpine based Based on a Mainpine controller, internally an ESP series microcontroller, possibly reflashable to Tasmota type code. Would do the MQTT part, not sure how to do the EV control part. This should have had a MCB / RCBO fitted as well as an isolator, although the feed is from a 16A socket with it's own MCB.000

Paxton Access card reader No luck finding how this can be made to work with Linux, as it shows up as a human interface device, I'd hoped it would emulate a keyboard, but if you can write a card as well as read one, that doesn't make much sense. A serial device would seem more likely.

SR201 network controlled module The SR-201 module is a widely available ethernet connected relay module. It is advertised as being “web controlled” in many outlets, but as I found out, it's not. I have written some python to allow it to be controlled via MQTT, this is available on Git Hub here:-000

Home Automation Background This is my first foray into Home Automation (if you exclude fitting PIR sensors to stairwells, toilets etc), so I've attempted to explain the terms and protocols I've encountered and sometimes found confusing.

Tasmota crib sheet Reset to defaults * Cut power from the device completely for 30 seconds. * Power the device on and off six times with intervals lower than 10 seconds and leave it on after seventh time. * Fast power cycle device recovery should activate and the device should be reset to firmware defaults.000
