I’ve looked at those many times and have read that they can be a bit persnickety, plus they are a bit bulky and pretty expensive for not having an open API. If you do get it working, i would be interested to know how it works with HA.
I’ll let you know how it goes. I just installed the unit last fall, still have to take it out for an extended period
How much BT stuff do you have working on that thermostat? Any sensors or controls yet? For me I got a BT external temp/humidity sensor that I could read in HA to know those values as sensors, I’m wondering if you have been able to even get that far yet.
Any luck on the LevelMate Pro? I added the propane sensors over this past weekend and wanted to do more. I am thinking of hard-wiring in the LevelMate Pro and then can leave it on to monitor the camper positioning - just in case I need to adjust or just to have more things on my floorplan lol.
I love your floor plan! I always have the plan to do that in my HA but never get around to it. What are you using for it?
No, I haven’t done anything with the levelmate yet, I’m going to sniff out the BT packets on that on my next refit in a couple of weeks.
On a side note, my initial proof of concepts on fully automating the 12V lighting is a success, now on to the prototypes. I wanted something that sort of “straps on” to the existing switches rather than having to cut new holes or use other switch types (both of which make things easier but mean you have to cut holes or have different button types).
P.S., our floor plans are almost identical. Funny. I don’t have the fireplace but otherwise nearly the same - kitchen layout, living room layout, bath…
Thanks! I started using @pkozul’s floorplan years ago for our home. I never got as fancy as some but literally use it daily. Floorplan for Home Assistant
Glad you are having luck with the 12v lighting. I had made some ESP32 controls with dimming that I could retrofit but ran into a major issue when I could only find a 12+ wire running to the lights: RV 12V Lighting Control - with Dimmer Switch control - #12 by yousaf465
Hope you share any success you have. I did try using a common ground but did not work for me either.
And GOOD LUCK with the BT sniffing. I tried on a Renogy unit a year or so ago and learned that I was not meant to do that stuff lol (aka unsuccessful).
That was my path at first as well, I instead went with Shelly Plus Uni’s and they are fantastic for this use, smaller than an ESP32 (even though they are one) and solid stay relays built in. Most RV switches are SPST with only ground or only 12V, you have to hunt behind the wall to find it’s mate. Fortunately almost all my switches are right in front of the entry and above the fuse box, so getting 12V + GND there isn’t too bad, a little more challenging with remote switches but possible. I’ll let you know as I go to prototype mode.
this is the circuit diagram for that project. although I have used wled with this one, esphome works the same.

It worked great on my workbench when I assumed I had access to both the + and - lines to the LED lights. Our camper is <1 year old and my wife was not too keen on my pulling out wall or ceiling panels to track down the negative wire.
I’m sure I will circle back to it eventually as I would really like to have both HA control and the rotary control.
Nor would my wife, lol. Nor me! I won’t be pulling luan down, more of just going to the destination, i.e., the fixture, and seeing if I can either trace it’s second wire to near the switch or find an alternate easily. I’m not going to start cutting wires inside the tiny 1 1/2" hole either, if I don’t find it easily then the lights don’t get automated.
For those following, some updates that I’ll write up soon for our 2024 season:
- Smart Thermostat (that works with the bizarre Dometic command codes) that works in HA
- Controllable 12v Switches (Lights coming soon, still some things to figure out)
- Dynamic Weather (this was a big one and I finally have a system in place)
- Extra Cooling without another A/C (tied into the smart thermostat to know when to turn on and off as needed when the A/C isn’t bringing the temperature down quickly enough)
Every year we bring the RV home for what we call our “re-fit” and then out for the “shake-down trip” which is just 5 miles away at a lake where we can run through all RV and boat systems to make sure our stuff is still OK and anything new from the re-fit is working properly - this gives us close proximity to local stores and the house to make adjustments before our first real trip.

Based on the fact that you’re using wifi devices to control switches, it doesn’t sound like you’re too concerned about power usage. Do you have a generator or plug into shore power usually?
I’m not.
Always one or the other. I have a genny big enough for everything that rig can suck up. 75% of the time I’m on shore power, 25% I’m boon-docking with the generator.
Did you get any further with Micro Air?
I’ve been monitoring the App queries and to be honest it looks pretty complicated with likely MQTT being used to send updates to the application itself. It goes via cognito-idp(auth), cognito-identity (session token generation), then dynamodb (actual query).
Im about to start looking at this from the Bluetooth point of view as it doesn’t look like a system they designed for others developing on.
Did you get this working/could you share it?
I did get it working mostly, there is still one last part I’m working on and then I’ll share the solution.

Cool project! I have HA setup in my 2006-era RV, but am mostly using it for remote monitoring while we are away from it. I have temp/humidity, moisture and door sensors all on Zigbee, and I am considering where to take it next. Giving HA access to my tank data would be nice, as well as lighting and hvac controls. When I am local, having data about connectivity could also be useful. I am sure I’ll come up with more as we use it more. Thanks for sharing your project!
Interested in where you are with this. I am setting up a new HA system in a “new to me” RV that also has the Dometic CCC 2 thermostat. Not as easy as it was putting the T6 Pro into my last RV with the older style thermostats.
Mine has two cool zones and one furnace so the adruino code would be different. Working with Adruino would be new to me. Does yours have multiple zones and have you made progress with the code?
Dometics use a special proprietary system so there are three real choices for them:
- Replace the board on the A/C unit itself with a Coleman, which apparently will allow you to use a standard thermostat but you might have to run wires
- Build your own 24v relay system using ESP/Arduino
- Get an EasyTouch RV smart thermostat (this is what I did)

Thanks, I knew of options 2 and 3. My understanding is there is no HA integration for the EasyTouch at this time though. Is that still the case?
