Now i flashed espurna 1.9.5 for my ECH1560 Chinese powermeter. (wemos d1-mini inside)
It is showing some values but it is a bit jumpy:
I have done the same mod (wemos mini wired directly) and it is jumpy as well just like your gif. Did you get to the bottom of this?

I ordered three powermeters and all three have a different printed circuit board. The 1st and the 3rd with spi interface, the 2nd with serial interface.
For the 3rd powermeter I made a pcb for the wemos and power supply, it just fitted in height.

How did you wire the 3rd power meter?

Thanks you so much!

I just recieved a power meter with an unknown chip. It's labeled with "BL6523GX". Does anybody knows if it's compatible or how can be hacked?

Thanks you!

Just a remark, I made the same 'mistake' viewtopic.php?f=38&t=7325&start=40#p149833 and added some opto-couplers between the powermeter board and the ESP for safety because I used ESP07 and external antenna's.

So it's better add the opto-couplers?

Only if you have external connections (like a WiFi antenna)

I can't make it work with a ESP-01...

Anybody has tried with this ESP?

ESP-01 has not enough memory i think. You probably get compiler/link errors?

No, I can compile and the code gets uploaded but I always obtain a 0 value in the voltage measure.
