I noticed that yesterday and some little bugs like upper/lower cases of some letters. I will edit the code now and also add some other codes. After this, I will work on the error messages.
I unpacked the 4heat app (unpacked app) and I found some .js files named controllers.js
it seems inside there are all the codes the app recognizes.
i also cleaned a bit the file. both files you may download them in here

Did you try changing the speed? usually, it is 9600 or 14400?
Also another code:
J30001000000000031 - Check Up
{% elif SensorCode == 31 %}
Check Up
I will change it now, in my 4heat 31, 32, and 33 is ignition. But checkup seems logical.
I have quickly scrolled throw the two files and can confirm tat this is the application code.
It consists of basically two parts, the local communication and the cloud communication.
Cause my 4heat interface is a branded resell of Oranier, we might get some more information if I unpack there App as well.
Keep you posted tonight …

With all new discovered States and two minor bugfixes
maybe we should unpack the latest app, this one i found online for download. The new versions maybe have the rest of the codes that are unknown till now.

I can confirm this one, I just saw it on my stove.
J30001000000000011 - Standby
I’m not sure how to verify J30001000000000008 - Safety but looking at the android app codes it is, yes.

I finally killed my Wifi module, it is stuck in a boot loop but before I where able to discover some commands.
There is SEC, which can switch on '["SEC","1","J30253000000000001"]', off '["SEC","1","J30254000000000001"]' and unblock '["SEC","1","J30255000000000001"]'.
With CF7 could the network information be queried the other CF1 - 6 look like configuration commands for the setup.
I have also unpacked my branded APP and the command JSON looks like yours.
The controller JS is a bit different but not much.
My stove returns 24 values:
SEL,24,J30001000000000006,J30002000000000000,J30005000000000357,J30006000000000025,J40007000000000000,B20364000000000007,B20575000000000001,J30026000000000378,J30012000000000000,J30017000000000072,J30020000000000000,J30084000000000001,B20381000000000005,B20385000000000000,B20493000000000030,B20199000000000072,B20225000000000055,B20369000000000006,B20570000000000000,B20369000000000006,B20365000000000030,B20366000000000075,B20374000000000045,B20375000000000070

As soon as I have back the wifi access I’ll test the meanwhile build integration.

I’ve managed to get some info on RS485 it uses RJ45 connector with the following pinout
PIN4 → A/+
PIN5 → B/-
PIN7 → +12V
PIN8 → GND
Regarding the protocol being used for screen is Modbus RTU at 19200
I was able to get some messages decoded with IONinja but modubus message lengths are all wrong most of them have length which is not multiple of 2 bytes and. And messages are somewhat fine until touch screen is connected. Connecting the screen starts returning all sorts of bad data and most of the messages have invalid checksums. But I was able to get some messages decoded when it send the firmware version of the screen on the bus.
Maybe they are using some sort of custom modbus implementation so a further debugging is needed. I’m working for the first time with modbus so any suggestions from someone with experience are welcome
In any way i think modbus is very complex protocol for remote control. Getting info on RS232 will be a way better solution but I don’t have the 4 heat module to be able to sniff the communication.
I have the module. It uses RJ11 cable and only the 4 wires in the mid. I think it is straight cable. How can I help? @najdanovicivan
First we need to find the correct pinout
RJ11 is 4pin connector. On NG21 board there is RJ12 which has 6 pins.
Does the module uses any other cables beside that one ? eg. external cable for power supply
Can you also check how many wires are inside the connector on the NG21 (Main Board) side and how wires are places. Eg colors/pin positions. Image of the bottom side of that connector will be useful
I found this video Installation 4HEAT MORETTI DESIGN - YouTube
So it uses only one cable. So we should at least have 4 wires, GND, VCC, RX, TX

Ivane,
i just took photos of the cable, as I suspected it is a straight cable and uses only the mid 4 pins. Here is the photo.
@zauberertz
Thomas,
I tried the wifi commands CF6 then CF7. After receiving the info of my wifi setup with CF7, the 4heat device went dumb, no communication, anything. Resetting from the power supply was not working, so I reset it via the button. During the setup with the app, the device didn’t save the config and was ready to setup again (blinking blue and red).
At some moment I tried and added fixed IP, instead of using DHCP. That worked. Now I use fixed IP.
Thats might the same issue I had with my unit.
I have been able to recover it. My problem where that it did not find its way back into my wifi. So I gave it a different IP at the DHCP cause the script was still running and tried to pull data. After completing the setup i switched back to the original IP and everything worked fine agin.
It looks like the CF commands put the device in a special state where you not able to pull data. Further more it causes issues when you do so.
I have build about 70% of the integration and hope to finish to night .
