I am trying to control my thermostat that is paired with my Smartthings Hub, so using mqtt. I have lights, switches, and power meters all running.
I just can’t find out what the correct syntax or setup would be for my config.yaml file.
Has anyone used a thermostat connected through smarttthings in their system, or could help me out?
I’m having the same issue, has anyone had any success?
Below is the code from the smartthings app, maybe that will shed some light.

that’s how i did it, and seems to work. i’ve got some input_selects to set a different temp or mode. here’s my config, although i don’t currently get the humidity state to come over, so still debugging that. “House” is the name of the thermostat device.
# House Thermostat

unit_of_measurement: 'F'
- platform: mqtt
name: House Humidity
state_topic: "smartthings/House/humidity"
unit_of_measurement: '%'I have tried the new MQTT climate function and that seems to only half work, it does nothing to update the thermostat and does not even post the correct payloads that I’ve specified. There seem to be posts of people saying they have this working but absolutely nothing about how to get it working. Posting new data to these topics does not affect the thermostat at all.
is the thermostat device assigned in the smartthings MQTT bridge app on your phone?
add the following to your config so you can see mqtt messages in your hass log file.
logger: default: warning logs: homeassistant.components.mqtt: debug
what kind of device do you have?
post your config
OK, so I finally had the time to sit down and sort it out. I had to pretty much build the thermostat interface from scratch because the default MQTT Climate controls do not work with my thermostat. The reason for that is that mine doesn’t have a single target temperature, it has a separate heating and cooling target and those must be set separately. I could probably create an automation that changes the setpoint for whichever mode it is in, but then I could never use auto mode if I wanted to.
If anyone has questions about this code please just ask, sorry if the formatting got messed up. One big tip for sending payload over MQTT, make sure ON is in the code as “ON” with quotes, otherwise HASS sends True as the payload.
The MQTT topics should pretty much be the same for you, but my thermostat is named “Thermostat” which you’ll need to change to match yours in the middle of the topic. EX: smartthings/THENAMEOFYOURTHERMOSTAT/tempurature

Any idea what I’m doing wrong?
Disregard, I was missing input_number: 
I was just coming to make sure you had that line. Glad you got it working!
found a few things that weren’t working for me…I had to put /state or /cmd at the end of a lot of your topics, but other than that, it’s working like a charm! Now, to find out if I can set auto temperatures based on this…
EDIT: looks like you can, lol.
Yup, I use them in automations and scripts. Piece of advice, never hard code temperatures into automations or scripts. Your comfort zone will fluctuate so it’s best to set defaults up as sliders and then adjust those as your preferences shift. I have a bunch of sliders for default temps whether I’m away, awake, or asleep.
Yup!! I have a fairly wide comfort level put in for now. I’ll have to take a look at scenes and automations later on, but I just wanted to see if this smartthings setup and some sort of auto temperature would play well together.
Hey, I know this is from a while ago now, but can you send me one of those automations you used for generic thermostat? Thought I had it down, apparently I missed something…
@roofuskit I found something I’m trying to fix right now - so the slider works great if it’s the only device you are using to change the temperature, but if you want to use automation, I’ve noticed it doesn’t change…at least, not the way I tried using automation. I also noticed that the thermostat mode selector doesn’t change. My solution is below

Any ideas on this would be appreciated.
