IoT race! Smart WiFi Thermostats @ecobee vs @nest for compatibility email/photo – GO! UPDATED!

Img 3888
On the Ecobee Smart WiFi Thermostat site you can click which wires you have on your thermostat and then an email is generated (you attach a photo) and you get an email back that will say if your thermostat is compatible or not. Nest does the same thing, we think they did that first, but either way, we sent an email to both at the same time, we’ll update the post and tell you which one got back to us first!

Subject: Compatibility Checker Result – System may not support full configuration – Please advise
Hello ecobee,
I ran the compatibility checker with a wiring configuration and the tool reported that ecobee needs to take a closer look. Can you please let me know if my system configuration is supported?
Please see the attached a photo of my thermostat.
My thermostat has the following wires: R, G, WW1, OB, YY1,

Hi Nest,
My wires are: G, O, R, W, Y
Am I compatible? I’ve attached a picture of my old thermostat’s wires to help.

Hello Phillip, thank you for contacting ecobee Support and for your interest in the ecobee3 HomeKit enabled thermostat.

Based on these connections you have a 1-stage heat-pump with 1-stage of aux heat, this is a compatible system. Because you do not have C(Common) wire the ecobee3 comes with a supplied PEK module, this can be used in your application however the O/B wire will not get connected through the PEK module but rather connect directly from the thermostat sub-base to the HVAC equipment directly.

See video & knowledgebase link for further instructions:

Let us know if we can be of further assistance.
