Looks like Wyze is coming out with a cheap ($50) wireless thermostat. As far as I can tell it is pretty similar to a Nest E. Apparently remote temp sensors are coming soon. [url]https://wyze.com/wyze-thermostat.html[/url] I do like that there is a C-wire adapter included in the box.

Right down to business. First post, cant find help anywhere on the internet and tired of waiting for Honeywell to respond. I have an old system in my house. I want to wire up a new thermostat. The current wires on the current thermostat are all different. Current thermostat Model Number: Intertherm T874r1202 Letters and wire colors: W2 - Brown X - Black Z - Blue G - Green R - Red K - Violet Y - Yellow T - Black W1 - White New Thermostat to be hooked up :Sensi ST55 Has these connections : RC, RH, O/B, Y, G, W/E, C, L, Y2* and W2* Current parts in operation(not changing) Intertherm Multi Speed Air Circulator Model #:901282 Intertherm Central Air Electric Furnace Model # FEB-020HA Outdoor Compressor Fan: Intertherm PCS050BA?? Not 100%, too hard to see I just need to know where the heck these wires go on the new thermostat.
