Is anyone interested in Arduino Yún as "room thermostat" for EQ-3 MAX! heating control system?
As far as I know, EQ-3 MAX! doesn't have thermostat with connection to boiler/DHW.
I'm using Yún as "actor" device for switching boiler/DHW on and off, depending on values from radiator thermostat.
If anyone using this system with Max! Cube, feel free msg me for details/sketch. Beta testers wanted 
Check this: GitHub - autopower/thermeq3: Boiler actor device for ELV/EQ-3 MAX! cube
It's still untested (except few days testing), but its working
Hello again, code is stable and thermeq3 is full of features. Take a look!
Hi autopower
just came across this posting & it looks really interesting.
I've just aquired an Arduino Yun, Max! cube & 5 wireless radiator thermostats & I'm interested in controlling my gas boiler as per your post.
I currently control a gas boiler/heat pump system using an Arduino Mega 2560 with 13 DS18B20 digital temps sensors. Two of these sensors replaces my 'normal' roomstat (one measures room temp from inside roomstat housing & the other at floor level. A third sensor measures outside air temp. I use an algorithm to adjust the required room temp constantly in real time & 'fire' the gas boiler or heat pump accordingly.
Unfortunately, these 2 room temp sensors are located in a South facing living room which experiences solar gain meaning the CH can be prevented from coming on even when other North facing rooms need heating.
Your system seems to offer a way around this problem by using individual or 'sum of' thermostat valve opening to turn the CH on, overriding the 2 temp sensors.
My big problem is understanding your system (I'm a retired mechanical engineer & my coding is limited to simple Arduino IDE)
" python-openssl library opkg update; opkg install python-openssl" - I don't understand this; can you explain (simple please)
"python code, upload into /root/ files nsm.py and config.py " - I run my Arduino sketches under Windows 7 so how can I copy the 2 files above into the /root folder ?
I have Ubuntu installed on my Win 7 as a virtual machine if that's of any use.
Hi Michal
I copied files nsm.py and config.py into the root of my Yun SD card; is this correct?
I uploaded your sketch to the Yun.
I changed the ip address in config.py to my Max! cube to 192.168.0.222 (as detailed on the back of the cube) using:
192.168.0.29/data/put/stp.max_ip = 192.168.0.222
192.168.0.29 is the address of my Yun
When I boot the Yun I do not see the flashing LED you mention.
When I run the serial monitor I get error messages:
Unable to connect: retrying (1)...
Unable to connect: retrying (2)...
Unable to connect: retrying (3)...
Unable to connect: retrying (4)...
Unable to connect: is the sketch using the bridge?
Please help!

Good luck.
Hi, for sure this is a good platform. But maybe too complicated for starting programmers.
