2020-09-02 An update to the home 1-wire network 1 year ago
For more than 12 years now(!) the house has temperature sensors using the 1-wire protocol. I recently redid some of the wiring between floors and I finally got around to rerouting the 1-wire network via this new route. I also added a temperature sensor in the big room in the attic, we are thinking of using that room more often. To get an idea of how good that idea is we wanted to get an idea of the temperatures up there and that's what I have 1-wire sensors for! I soldered an 18b20 sensor to the end of a 4-wire flat phone cable, added it to the network and it's measuring. So now 12 environmental temperatures are measured every 5 minutes: 9 in the house, one in the weather hut, one in the shed and one on the roof of the shed. I also updated the 1-wire projects overview with how I use 4-wire flat phone cable in RJ45 connectors for 1-wire network. I had to look up how I did that previously before I could start adding new cables!
