which firmware version do you have ?
Please check attached latest MQTT version firmware v2.02. with this firmware you need to use the new App - Myhouse Pro .
firmware download link
https://we.tl/t-C2z6RgN3aC
To set the MQTT server below is the operation:
1 ) go to the menu - Screen Lock ,input the password 1976
2 ）press the “Lock” button to enter the mqtt server setting screen
3 ) press the button “MQTT server” to modify the current server name() to your own mqtt server, for example you can input 192.168.1.288
4) the topic is fixed , that is Heat
5) please note if you dont input new mqtt server and this is the first enter this setting its better to press the second button “Reset to factory setting”, because if you go back to home screen the firmware will looking for the new mqtt server in E2 chip , normally this data is wrong if it is not written by anyting, this means this mc6 would not connect to our mqtt server and App would not work.
The OTA function is avilable from this firmware .
the new touch hardware released began from early 2020.
I have:
2 x 3.16z
3 x 3.09z
2 x 2.98
2 x 1.10
1 x 2.02
I’ve programmed with this new version, and it is connecting to my MQTT server.
I’me receiving the messages in the topic /updData/5002XXXXXX with messages that look base64: g2uLL8wDFwb/AQ96VKST1ef9ShKFuTxcSOQqgk8ej7Q=
Is there any trick to convert them?
sorry, yes, the topic is updData , that 5002xx is this MC6 mac address.
the data is encrypted with AES256, we will upload a new firmware which you can set the key or select none-encryption next week.
attached picture is the mqtt data list

Hi MateusZ
This link is the MQTT firmware for common MC6, it connects to our MC6 cloud server , the data is encoded by AES128, user could use our App - Myhouse Pro to operate this mqtt MC6.

Please… anybody know why my AWAY and ON/OFF button didn’t work?
Hi, sorry for the error in he blog. I have updated with the correct code. Here you are:
switch:

name: "Termostato On/Off"
state_topic: "home/termostato/status/state"
command_topic: "home/termostato/status/set"
value_template: "{{ value_json }}"
payload_on: "1"
payload_off: "0"
qos: 0
retain: true

//History is same problem. 
for history:
sensor:
- platform: mqtt
name: "termostato_mode"
state_topic: "home/termostato/mode/state"
value_template: "{{ value_json }}"Do you mean this?
sensor:

Domaray thank’s. Now is fully work.
Is there any way I can add +/- buttons to change the temperature?
@Domaray thank you for your blog post about MC6 and HA!
I have a question, does anyone have issue with connectivity ? Or is there a way to debug what is going on if integration is not working as it should?
You can see history how it behaves, last data is from 4 hours ago, previously from 9 and 16 etc. but I’m trying to change the temperature, turn it on/off, set to away, basically everything that integration offers, without any change on the MC6 and without any change in history
How it looks like when I change temperature
