SD cards are in normal operation mode, besides of one card failure after one month (some factory defect I suppose), everything is fine. We will see when do the life cycle of cards expire, a year is behind us. I tested power-off events many

Relay modules from finder, custom pcb modules with current outputs for switching relays and optoisolators for voltage detecion, some custom expansion module for all signals interconnection. I will prepare some appendix to the blog-post with

RPi is only accessible in separate local network. Doors also has regular locks which are used after working hours. In case of sytem failure almost all parts has alternative working conditions: lights can be controlled with wall switches, rf

We were aiming into easy customizability at high level code and I couldn't find any commercial system meeting this requirements. I'm very much into open-source, so thank you for those two solutions. I haven't seen it before.

And for those cases I decided to place wall switches in parallel. As automation fails you can still operate all lights with classic, wall switch, way. Also, solution for jamming relays are SSRs. In practice there were issues only with two b

Exactly. Price level of our system is incomparable with same solution based on KNX. Future modifications and changes will be easy even with support discontinuation from our side. Every part of the system is modular - you can pull out RPi wi
