So, if I'm understanding this correctly, this thermostat shuts down the fan and compressor together by sending a "shutdown" signal to the unit by mimicking off button on the unit's remote? 

The  Cielo is independent of the remote and actually turns OFF the power to the Atmos 1° below the low temp setting then turns ON the power to the Atmos 1° above the high setting. There is zero power draw during the shutdown period. When using the thermostat, the remote must be turned OFF and the phone app used to control. The remote can be used for normal operation of the unit, but for enhanced features like Comfy Mode the app is used. Selecting the proper temp setpoint will determine if the fan or compressor runs longer at shutdown. I will address that another time. There is also a Comfy Max Mode, which mimics a home HVAC set for heat/cool, but I think the fan is continuous. Did this answer your question?

That seems like a perfect solution to the "always on" fan issue! Shouldn't this thermostat work for other units that have a remote control to control them?

As I understand it, the Cielo line of products is primarily marketed for mini splint air conditioners, but obviously found to be comparable with other types. SDG that sells and installs the Drieha Atmos 4.4 uses these IR Cielo thermostats in some of the Class B RVs they mostly deal with. I haven’t read of any other brands of rooftop units being controlled by a Cielo, but guess it may be possible. I agree, a perfect solution!

This is from the description on their Amazon store-

"Product Usage Instructions: Breez Max connects to a 2.4 GHz Wi-Fi network. It is compatible with any mini-split, window or portable unit that has an IR remote control. If your device doesn't work out of the box, please contact Cielo Customer Support to make it compatible."

Looks like any unit that works with an IR remote has a good chance of working with this thermostat. Might have to start a new thread at some point to track what other AC units it actually does work with? Thanks again for this.

In said mode, once custom temperature or humidity comfort ranges are dialed in, the Atmos will turn on power when the high setting is exceeded and subsequently turn off power when the lower setting is exceeded. This is ‘HUGE

I didn’t think I needed this since already having the remote and other app control but I believe I am going to try it. Being able to more clearly refine the control is what we all want.  Thx for sharing the product and evaluation. 
 

… now, where to place it? USB power makes things interesting.

The Cielo has to be positioned for line-of-sight with the Atmos controls in the air distribution panel. And yes, an AC outlet or USB port is needed in close proximity; however it is equipped for hardwiring. When learning how to use the Cielo, I sat at the dinette and plugged into an AC outlet via the supplied 5V adapter; the supplied base stand for flat surface staging was also used. Being a wall-mount is best securement in a rolling earthquake, I first tried it on the forward bulkhead to the upper left of the wet bath door, but didn’t like the cord dangling down the wall and it seemed a bit less responsive due to the distance. I then placed it between the two curbside upper cabinets near the under cabinet USB ports above the cooktop, but the 90° orientation didn’t work as well and there would be concerns of rising heat if cooking. Finally I placed it as shown in the pic, whereby the cord runs in and out of the galley cabinet and plugs into said USB port. I used Velcro for the mount, and may eventually hardwire the Cielo through that upper cabinet and tap into the wiring within the access screw port for a cleaner installation. As positioned, the Cielo is in clear view from bed, and I like that the backlight is dimmable or can be turned off.

Good idea! It also claims ‘The smart air conditioner controller is compatible with over 20,000 models of mini-splits, window, or portable units’. Maybe there will be some owners of SOB units willing to try the Cielo Breez Max and report their findings.

It would be very interesting to see if it works with the Houghton units. Hopefully someone with one will see your solution and give it a shot.

The ONLY good thing re the Dometic P2 is it does turn off when fan set to AUTO and temp is reached!

The problem starts every time it starts back up! 😆 I know this is a very individualized thing but I actually like the unit and/or fan only running continuously, especially if it is quiet. It was the loud start and stops of the DP2 that woke me up during the night, etc. I am very hot natured and live in the humid SE. What Ron has figured out is better than the other options of timing out, manually shutting off the unit, or using the AUTO mode with no ability to refine temp settings. Hope everyone has a great weekend!
