Sorry for another thermostat project. I guess it's that time of year.
I thought I would move onto the project section seeing as how I've got my little project just about working with lots of help in the troubleshooting section (very gratefully received).
To outline it, I have a Pi 2 B wired to a breadboard of components including a temperature sensor and I access it via Putty. I send a Gmail a temperature and it basically operates a relay and loops until the sensor achieves the Gmailed temperature and then it operates the relay again.
I'd like to develop it further and for the following reasons so I will be having a think/read/play and any suggestions would also be welcome.
1) I'd like some remote facility in the system for the fact that at the moment the whole lot would have to be in the boiler cupboard and obviously, the temperature in there is wholly different to the temperature in the living room. Ideally I'd like the relay separate and connected to the boiler and keep the Pi and temperature sensor in the living room but I don't know if that's feasible.
2) At the minute once the system achieves the target temperature, that being the one I Gmail, the system closes down but then switches back on once the system falls below that target again. So, due to the heat loos in my house. It could be that the system reaches 21C, turns off and then literally minutes later comes back on for a few minutes and then off again and so on. This isn't very efficient so I'm thinking of messing with the code a little to put something in to say once the target is reached then do not restart again until the sensor detects the target temperature minus 4, or something similarly.
3) I'd like to possibly be able to read the temperature that the sensor detects remotely again, on my mobile so that I can see what temperature the house is at in the first instance before sending a target temperature by Gmail.
I'm still only very new at all this and so it's a very very steep learning curve however, I'll persevere to the point of complete confusion.
