I was contacted by an representative from ITEAD about testing some new equipment and write an unbiased blog post about it. I usually reject all such offers, but this one worked for me. Why? Well, all the stuff they offered was on my shopping list anyway! And my home is quite literally chock full of Sonoff relays, lamps etc.
So the first thing I started to play with was the SONOFF RF BRIDGE 433. This makes it possible to control switches, door bells, curtain openers etc that uses 433MHz communication frequency. I’m not interested in using the original firmware because I prefer to do my home automation setup in Node-RED. Here’s how it works.
