I currently have a warm water heating system. Currently the controller monitors:
a. Outside temperature
b. Inside Temperature
c. Temperature of the water
It determines the water temperature by a formula that includes the outside temp, inside desired temp and a maximum water temp not to be exceeded along with a mean average low temperature of the locale. The controller also opens and closes a valve that mixes the return and source water to get it to the desired temperature for the floor radiators. I do not have the formula worked out yet, just asking if RM4 is up to doing something like this. All safeguards are in place outside the pervue of the controller, so that the Hubitat is not responsible for those. What do you think? I am thinking of working up a Arduino to get the relays and the temp sensors connected.
This sounds like something that should really be done by a driver or app that could perform the math in one step. The problem with using RM to do any type of computation is that you can only do it one step at a time rather than all in one expression.
If you're looking for a project to encorporate an Arduino, you should search for Hubduino here on the forum. Absolutely quickest and easiest way to build an Arduino based device for Hubitat. The libraries includes support for just about every sensor and actuator you can think from Temp, motion, lux, ultrasonic, photoelectric, contact sensors to relays, switches, dimmers (pwm) and many, many more.
Hi Ryan,
I would need alot more studying to create an APP :)) , but I am sure you are right. I will look into making my own. I actually am already using Hubduino with my Hubitat for other things around the house. I want to have the Arduino devote all its energies to keeping the house warm this winter.
Thanks
