No stove connection during initialization byte 0x201c in iGetStatusAtech function

[dxmen7]

Hello, I have following issue, I have debugged every single line until Palazzetti.cpp line 1013: Palazzetti::CommandResult Palazzetti::iGetStatusAtech() { CommandResult cmdRes; // die zeile gibt nicht erwarteten wert zurück cmdRes = fumisComReadByte(0x201C, &_STATUS); if (cmdRes != CommandResult::OK) { Serial1.println("fumisComReadByte(0x201C, &_STATUS) != CommandResult::OK"); return cmdRes; }

Here the controller tries to read byte =x201c and expects specifc byte value, but this failed. Without knowledge about Fumis byte structure it's difficult for me to go ahead. DO you have an idea or more background knowledge about Fumis byte structure?

I have a Fumis Alpha UI from JOTUL stove connected to Fumis controller, where I connected my RJ11 cable to my controller. If you need further information, please let me know.

Debugged serial Rx/Tx on stove and µC side looks fine.

Hello,

What is your motherboard model?

[Domochip]

I can only imagine 2 scenario :

• there is a problem with the adapter and/or cable
• your motherboard is not compatible

Could you give me more details about your motherboard and explain how you cabled it?

[dxmen7]

Hello,Thanks for your reply. Yes I will give you my motherboard model number this weekend, I have to partially dismount my stove. I checked the adapter several times with a friend together and measured every single element. In my opinion, there can be a risk with a newer hardware version from Fumis and potentially an incompatibility. On 4.

Sorry,Forgot the second part. Cabled it by RJ11 cable and modified as you described in your repo with crossing the lines.This cable goes to adapter, adapter is on top of D1 Mini and d1 mini Ports also correct.With serial monitor I have checked Rx and Tx on both sides and can see an Tx by D1 Mini after receiving an Rx and vice versa from stove side. On 4.

ok, in that case I advise to take some pictures too at the same time you open it ;-)

[dxmen7]

Hello from Germany,

I was not able to open side panel for direct access to motherboard. I only have model type, vendor serial number under device model of UI panel at the side of the stove. Maybe this help you too. Attached pictures how is the controller cabled to stove. I will try gonget more information and manual, how to open side panel.

Please find here iCloud Link to pictures, attaching to mail is too big: https://share.icloud.com/photos/012Ni27n0eGaETrfiNwn6vIIw

Best, Dennis

Hello,

When you plug the stove to the module without powering the d1mini, do you see the D1 diode blinking (activity of the stove bus)? does an error appears on the stove screen after 10sec? Same questions but with the d1mini powered?

[dxmen7]

Hello, Yes, LED on stove side is blinking and confirmed with bus analyzer, that Tx and Rx are transmitted and received frames. D1 mini powered also. NO error on stove side after 10 sec.

What's your Jotul stove model? Do you know if Jotul offers a "ConnectionBox" or a module to control it via mobile phone?

[dxmen7]

It’s Model PF733 from Jotul. Yes they offer a WiFi connection box with mobile app for one 200€, that was my trigger to try it by myself with your repo.

Service man also have a RJ11 cable with him to control stove via proprietary software provided by Jotul. Connection box link with Jotul App you can find here: https://intl.jotul.com/sites/importers/files/products/JOTUL_PELLET_CONTROL_Manual_EN.pdf

OK, it should definitely be compatible with my module.

few seconds after powering the d1mini, you should see D3 led blinking shortly. Is that the case?

What's appears in the web page?

[dxmen7]

Yes, D3 LED is blinking shortly after powering up. Web Page looks like this:  Uptime currently less than 1 min. But also after 5 mins same behavior.

The webpage image does not appears. could you paste it in github page directly pls Which firmware are you using?

[dxmen7]

I am using firmware 2.1.5/3.1.2

[Domochip]

OK, log is going out of D4 pin at 38400bps First you can have look at what's logged.

Do you know how to create a platformio/arduinoIDE project and compile it? if yes, I advidse you to use this very basic example : https://github.com/Domochip/Palazzetti/blob/master/examples/Serial_esp8266/Serial_esp8266.ino if No, I can compile it for you

[dxmen7]

Yes I have compiled it with Arduino IDE, but don't get any useful output. tried different Baudrates for serial monitor

[Domochip]

What output do you get?

[dxmen7]

load 0x3fff20b8, len 40, room 8 tail 0 chksum 0x2b csum 0x2b v000471b0 ~ld rf cal sector: 1020 freq trace enable 0 rf[112] : 0� With Baudrate 74880.

Output form D1mini only endless ASCII symbols, which cannot be decoded in serial monitor.

[Domochip]

baudrate is 38400bps

[dxmen7]

this with Baudrate 38400:

b q!!i% H N%/�ayFC�g!n5)%oX %1-�,:!9Bg!yk)1%oC!1)B:1)J�)J){ B�)s'9 H:�=H+?))�

[Domochip]

the log is coming out of the D4 pin. you need an additionnal serial adapter connected to GND and D4 to receive the log

[dxmen7]

yeah was my fault, I will get one and come back to you

[Domochip]

no problem ;-)

[dxmen7]

Got it, unfortunately everything failed :(

wSer started initialize Failed myPala.getSetPoint failed myPala.getAllTemps failed myPala.GetStatus failed

[Domochip]

do you have a logic analyzer?

[dxmen7]

A friend of mine yes. What do you need for information?

[Domochip]

The goal is to monitor exchanges on tx AND rx of the d1mini with real timing. That's the ultimate solution to debug what's happening.

Another idea would be to use 2 serial adapter one on D6 and one on D7. But it needs to log the precise timing to be able to reconstruct the "discussion"

[Domochip]

Hello, could you also try to remove R8 resistor or D3 led?

[dxmen7]

Yes can do it. Since today also have the logic analyzer and check tomorrow

[Domochip]

also what's your si8621 exact model (2 letters after 8621)?
