OpenDTU want connect to inwerters

[cypel21]

Hello,

I can't connect to the inverters.
The inverters were never connected with the original DTU. I decided to switch to OpenDTU right away. I installed it on the ESP, connected the antenna, added an inverter (one of two at the moment). Unfortunately, nothing. I got a sunny day. Inwerters are HMS-1600-4t

E.T. is listening on 860 MHz but not Hoymiles. Please start with the default frequency for Europe on 865 MHz.

@ms49434 The problem is that I have set 865 MHz, and it make only one check. After that switch to 860 MHz

Looks like a wiring issue

[cypel21]

Hmm maybe. Strangely it shows that everything is connected good

[cypel21]

What pin can be wrong, but opendtu will say it is connected?

[cypel21]

I found a solution.
It turned out that I had to disable pins 2 and 3 in the pinout.
Immediately after I set them to -1, everything started up. Thank you all for your interest.
