433mhz Automation

I’m currently using a similar setup to monitor a 433MHz fuel tank sensor, rtl433 is a great project.

SONOFF make a Wifi RF Bridge which has a 433MHz transceiver and can be flashed with Tasmota, I’ve experimented with it for controlling RF controlled lights.

Broadlink also do RF transceivers, although only used their IR devices.

RFXCOM has great transceivers for 433 MHz. I've been using them for over 15 years.
