I started my home automation hobby about 6 years ago with Pimatic. Since a year I’ve been working with Home Assistant and have now converted all the plugins that I had written for Pimatic to Home Assistant integrations.

Homeduino is an Arduino sketch that was developed by the Pimatic team to control 433 mHz devices using an Arduino and 433 mHz receiver and transmitter modules. KlikAanKlikUit switches, dimmers, weather stations and those kind of things are supported. The Homeduino costs about € 10 in materials to make, so it’s also a very budget-friendly solution.

I still have a number of 433 mHz devices lying around, but I didn’t feel like investing in new hardware to control them with HA.

Long story short; I have programmed a Homeduino integration for Home Assistant and I have the first lamps, switches and dimmers working. To be precise, all the devices I still own. For many protocols I don’t have test devices, so it is a bit difficult to test those protocols.
