Error: Unknown Shine Stick

[Folllast]

What happened?

My Inverter MIC2000 is running. The green leaf is lighted and i see the power etc. in de Display. But there are no values on the GroStick. every value is 0 and the status is 0 (Waiting). I changed nothin on the setup.

Stick type

What Stick type are you using?

• USB Shine Stocl

Which Inverter are you using?

• MIC-2000-TL-X

Log output

Please copy and paste any relevant log output from /debug and the serial console (You have to compile the firmware with the relevant settings in Config.h to get the output).

.... I changed nothin on the setup.

Are you using the precompiled firmware? Did you do an update and was it working before?

[Folllast]

Ir was working for 2 months. I installed the precompiled firmware.
I am pretty sure that the stick does not have an automatic update function and that the inverter cannot update itself via the stick.
A few days ago it snowed here and the inverter was off for several days. Now it is running again, but the stick is not supplying any data.

Today I had a similar issue with the same error message. this was working for the past 4 months with no issue. nothing changed as far as I can tell, I didn't upgrade etc.
My inverter is a MIN 6000TL-X. My logs already rolled but I saw the same Unknown shine stick. about 20 min later everything started working again. I did try few reboots and physical disconnect which didn't help but on it's own it all the sudden connected fine:

I'm not sure how to enable ssh to get more logs...

I have the same issue; it worked fine for a couple of weeks but suddenly a 'unknown shine stick' error pops up. I use a Min 4200TL-XE inverter and a Wemos D1 mini connected via USB. The error is there for a couple of days now; resetting / disconnecting the D1 mini doesn't solve it.

Sry for my late response. Please make sure that serial debug is disabled. As it puts out log messages on the same serial port which is used for the modbus connections (I always wondered how this is working at all).

There is a baudrate autodetection feature in the code I do not really trust. We could try to disable this. Anyone willing to test that?

[theguardian85]

I've just recompiled the code for a D1 board, uploaded it and it working again. More than happy to do it again without the baudrate auto detection.

Fyi: While recompiling, PlatformIO did had issues with line 37 in ShineMqtt: return HOSTNAME + String(id & 0xffffffff); -> the String(id & 0xffffffff); gives an error.

1. Where should I disable the serial debug? in the Inverter or on the Stick? is there a register to disable it via stick?
2. If there is a fixed baudrate in the WR, maybe a fixed baudrate in the Software should be more stable.

[crasu]

1. In Config.h - Debug is disabled by default if you use a precompiled image
2. I made it possible to set a fixed baud rate via the Config.h and attached precompiled firmware images (for shine stick x) to this post. Feel free to test them - feedback welcome.

Today I am experiencing the same 'Unknown Shine Stick' message for my Growatt MIN2500 TL-X.

I am running tests on the ShineWifi-X as well as on a brand new NodeMCU V2.
Both seem to fail communicating with the inverter.

This is my log:

I found another Issue about this, suggesting I should change the slave id to 4. I tried this without success.

I am compiling using the ArduinoIDE.

By the way, how do I know which versions of modbus I should compile?

Any suggestions are welcome!
