I had some old 433 MHz plugs, so I've decided to buy and setup the Sonoff 433 RF Bridge to control them via Node-RED / Google Assistant.
And I planned in the future to use it for meteo station.
Unfortunately the build-in firmware is supporting only Sonoff 433 devices and the custom firmware are almost unusable due to extremely small list of supported devices.
Conclusion: don't buy - isn't worth the money and effort googling for any solution
