Project Stereo 3 [alarm] (Projekt Hifi Anlage 3)

... and we did it! It is the opposite of a wonderful morning if you have to wake up at 3.30 h. However, the last time it was terrific. At 3.30 h my bedside lamp came on. Ok, this is not that nice. But then we heard from a near distance the sound of boiling water. Two minutes later we stood up and had our first fresh cup of tea. The next time we will have a coffee machine connected to the wireless socket! And in a few months I will get a hot chocolate machine! And then we will have coffee, cacao and music!1!!

Project Stereo 2 (Projekt Hifi Anlage 2)

A set-up consisting of a stereo system, Raspberry Pi, a 433 MHz radio transmitter and Elro wireless electrical socket now works. We followed this HowTo (German) and had to look here for connection of the Raspberry pins to the sender module.

Today we wanted to be awakened by a cron job of our raspberry: Well, the pi did not do his job. We used rcswitch-pi. It seems that if you use two send commands at the same time (or too fast in succession), they won't work. Tomorrow we will try again!
