Connection problem #5

I have tested my set - power meter + RS converter + raspberry on my desk, connecting 1 phase and 1 device and it worked. Now when the SDM is installed in a 3ph power grid, having connected everything up I received such error and no readings:

Everything - cable, converted and domoticz is the same. It was just installed. Checked the cabling twice

Did you use an FTDI cable or the cheap China version?

piotr333k commented 4 years ago

Ch341 chip, approx 6 USD. I suppose it's what you mean, a cheap China cable. Does it really matter so much?

It matters a lot! Ditch this cable and buy an original FTDI and all your issues will be solved. I used this China version too for about one year. It seems to work, therefore I always thought the issues (weekly hangups and random no communication after days of working correctly) were caused by something else. But after changing to the FTDI cable it was stable as a rock and no issues at all anymore!

I'll order a good one and check it.

FTDI cable solvet everything, works like a charm.
