Hello,

Until 2 days ago, my setup worked smooth. I could read all the data of the battery, MPPT, WR via the web interface and could see updated every 5 to 10 seconds.

Yesterday, the communication became more diffuclt. The only 50 % of the data for the WR are transmitted, sometime with 1 minute interval. The data of the MPTT are sometime transmitted correctly, or only 1 out of 10 values is received.

my setup:
MPPT 100/15
MPPT 150/35
OpenDTUfusion :

Pylontech US3000
Hoymiles HM-600
IR Power meter HICHI (data transmitted per MQQT)

Yesterday I rebooted the DTU (power cable out), and received for some time good data again, but it stayed stable only for one hour.

I could observe via Home Assistant that the DTU disconnect periodically:

Below is a short extract of the console, where we can see 2 gaps in the data transmission (marked with BREAK)

Even if I cannot get the data, it looks like the limit of the WR is adjusted to the value of the power meter, since my grid consumtion is ofter close to 0...

My assumption is that this is a communication issue between the DTU and my rooter, but I dont kown how to test it or to make it works as good as 2 days again...

Does anyone has a clue ? Should I check for other values ?

Many thanks !

Regards, Grüße

Hello @Kukusse,

The data of the MPTT are sometime transmitted correctly, or only 1 out of 10 values is received.

I assume you use the OpenDTU Fusion CAN/Iso Shield to connect the Victron MPTT. How long is the cable?
You can also try to disable the "verbose logging" for the solar charger and check if you still see the breaks in the logging.

Thanks for the replay. I use indeed the OpenDTU Fusion CAN/Iso Shield to connect the victron MPPT. The cables are a simple jumper cables, so approx. 20 cm long.

I checked disable the "verblose logging", but still have the breaks of 10s in the logging.

The ouput of the inverter looks like:

Up to day before yesterday, I had a continuous curve, not a dotted line.

Since the problem occurred suddenly, at the time I wasn't changing any configuration nor playing with other ESP32, I suspected an interference from the outside. I will change the transmission power and frequency of the CMT2300A.

In the same time, I changed the channel of my wifi WLAN. Now it looks good, but I will wait at least a couple of days and report the results here.
