Hi! I would like to create an app to control the temperature in my garage to avoid condensation when the outside temperature gets warmer than the indoor temperature. Therefore I need to be able to input a bunch of settings like delta temperature (indoor temp - outdoor temp), hysteresis, indoor max …

No need for coding a new app. Make the calculations with better logic app or the Homey build in logic and control the fans and/or heaters based on these calculations.

Agree, or use Homeyscript to do the complexer calculations. If you do decide to build an app, the SDK documentation is pretty good IMO but you will need some programming experience. If Homeyscript is too much for this problem, no amount of tutorials will make it easier as a full blown app.

I would recommend to give the vThermo app a try. The delta’s can be calculated using logics math.js like said before. Example: (“temperatuur is veranderd” means “temperature has changed”) Logics condition card (the And card) “A comparison is true”: [Screenshot_20211113-221710_Homey]

There is a mold detector from POPP available. It’s function is based on the measurements of temperature and humidity. The sensor isn’t supported by the POPP app yet, but you could ask the developer to add the sensor to the app. The sensor uses Z-Wave. So you have also to check, if Z-Wave signal is a…

Wow, a lot of answers! :slight_smile: Thankyou all. I will have a look at all this. I’ll probably get back with more questions once I have installed all the devices needed. :slight_smile: Thanks again.

Btw, which temperature and humidity sensors does this app (VThermo) support?

You’re right Peter. Don’t know why I didn’t found the app this morning… :man_shrugging:t3: Sorry for the false information.

The Insight Trends app is worth having a look at too.
