Can't seem to find any of the HMS 1600 4T inverters

[MirandaV89]

Hi all,

I've ordered the blinkyparts items (presoldered CMT module). Everything seems to work fine (CMT module connected and configured, WLAN and MQTT works).
However, it sends packages, but never gets anything back, not for any of my four HMS 1600 4T inverters. Based on the serial numbers, they are identified correctly as HMS-1600/1800/2000-4T.

I've read the troubleshooting page and tried all that. Furthermore I had a look at the issues and discussions tab, but could not find a solution there.

In case this helps, here is some of the console log:

(btw, yes, the inverters are still on, although not converting much)

Thanks in advance for any help,

I tried even more locations in my house, that didn't work.
Then I opened the window and finally it found the inverters.
Maybe I need a stronger antenna, but good to know that in principle in works.
