Is support for the 100/50 available? Is there anything i can provide to help you make this work with this version? I have configured as outlined in the docs but receive nan for all items.

Please make sure the logger doesn't write to the same GPIOs (by default).

syssi commented 3 years ago

Hmmm.. please ignore my comment. It shouldn't be an issue.

I tried commenting out everything under logger: I tried UART1 also. Both do not work. I checked victron app for tx function and it is set to normal communcation. Anyway to see if anything is coming out of the tx port of 100/50 into rx port on d1mini?

@drawlusyk please describe the connection between wemos and mppt and how to power the wemos

FYI i tried on an esp32 and got it working straight away. Given the tcp buffer error above on the d1mini it might have something to do with the d1 specs.

KinDR007 commented 3 years ago

Please 24v in is the battery connected to mppt? if so, disconnect gnd from the ve.direct connector

And look here HA ve.direct

if gnd cables are wemos connected? so is disconnection! connect ground only with stepdown and with ve.direct port take tx pin only and disconect all pins except tx !! No 5v no gnd (if batt its connected to mppt ) no RX only tx pin !!!

KinDR007 commented 3 years ago

@drawlusyk any progress?

drawlusyk commented 3 years ago

Since it works on the esp32 and not on the d1mini I have, i believe there might be some spec issue with the d1. (Message skipped because it was too big to fit in TCP buffer - This is only cosmetic) this message only shows on the d1. Its an aliexpress purchase. If i have time again in the future i will keep pursuing but this stage i will wire this to the esp32 to get the data. Thanks for your support and looking into it. Great to see that you have done this for esphome!!!

@drawlusyk it's weird, i run both mppt and smartshunt on wemos d1 and it runs as it should so .probably the wrong piece in your case
