Note to self: don't forget to frequently check your Homematic domotics system for any heating related issues...
2nd note to self: don't forget. But I did. Sigh.
3rd note (to visitor): skip this page. It's just for my own usage. You want to go here and see what else is on offer...
Upfront: this is a bit of a kludge, and I'll be looking for a better option, as soon as I can find one. But it taught me things...
Anyway, with the ever-increasing price of electricity, I was wondering if I could not simply switch off my home server upon command. In the past, I used a timed-out, which worked fine, but there are other users in my household, and they're not always computer-savvy.
In de handleiding van de nieuwere versies van de WHR950 staat een aansluiting voor een badkamer schakelaar beschreven. In de oudere versie zit deze functie ook, zij het iets minder duidelijk aangegeven. Zoek op de print naar de aansluiting DI2L. Dat is 'm!
Hierbij mijn 'mini' projectje om de WTW installatie automatisch in de hoge stand te zetten wanneer nodig. De principes werken natuurlijk ook met andere merken / producten.
Well, actually they mess up diagrams, but this title sounds better 😅
My Homematic CCU2 collects data and displays them in a diagram. I had added an additional Temperature / Humidity sensor in the bathroom (for a future ventilation project) but sometimes an error was displayed, about some 'data missing'.
My house is using a centralized ventilation system (a WHR950) with three operating modes. You're supposed (!) to switch to mode 1, 2 or 3, using a switch in the living room, whenever needed... which no-one ever does.
I was wondering... could I automate this?
