the smh series works so i think, can you explain your wireing, photos and more

The connection is made as you see in your diagram... On pipsolar it works well and I don't have any problems. I switch to SMH and I can't get it to work

pipsolar have a lot of implemented protocols, i dont have all at the moment. without know what your device speaks i cant fix it. double check your wireing for twisted data lines and/or try to swap it

I just find it strange that the pipsolar I have (pip30) works fine and when I change to the Easun smh II 4.2kw it stops working. But ok I'll check the connections but I'm almost certain that it's clear that the pipsolar where it uses the pip30 protocol works fine.

avenseElectro avatar Oct 20 '24 14:10 avenseElectro

Pipsolar have a Lot more as the single pi30 Protocol, WE need to find Out what your device Talk in Details. Can you get a RAW or debug Log of communication from your device? Or use watchppwer to created a communication log

I've tried several times and re-read the connections and they're all ok. Remembering that just connect to the pipsolar inverter (pip30 protocol works) Tell me how to debug watchpower....

start watchpower, right click on the litle icon on the task bar(next to clock) and click on debug, a folder opens. when watchpower is connected and read data the folder will fill up with files. zip it and upload it here

thank you, so the little problem is simple. i ask the devices for QPI the most answer with 18 or 30 was the protocol version is, but yours doenst answer with anything. short crude fix, but try it Solar2MQTT_1.2.0-Pre5A3_OTA.bin.zip

Unfortunately it also doesn't work with the version you sent.

But you have it on your github stating that this inverter works.... Why isn't mine working?

possible that your device have different firmware what tells the web serial now?

thats curios. so i send the same QVFW comand as the watchpower but your device answer with NAK lets try with another comand Solar2MQTT_1.2.0-Pre5A4_OTA.bin.zip

ok your device speaks a different language, it answer on all with NAK yes that interrupt, have some exception that i dont find, its a bug for later. so last try is to get a raw communication snipet from your com port of the pc, it exsist some software that can do that

edit: can you see the com baudrate in watchpower? edit2: you can try this https://github.com/syssi/esphome-smg-ii/ its modbus variant, just for try, or pipsolar.

wait ... the default speed for PI protocols is 2400, so thats fucking fast. let me build short a version that changes to 19200

softwarecrash avatar Oct 21 '24 20:10 softwarecrash

changes on QVFW querry to 19200 Solar2MQTT_1.2.0-Pre5A5_OTA.bin.zip

dont know its a typo error or right, at the top of it stand modbus settings, so its possible that you have a version that speaks modbus

I would suggest removing this inverter model from your "inverters that work"

my inverter is that https://pt.aliexpress.com/item/1005006361049535.html?spm=a2g0o.order_list.order_list_main.5.4dbdcaa4ncfHFi&gatewayAdapt=glo2bra

try to aks your seller for the comunication protocol, thtas was helpfull too

not so fast ;) so here someone wrote that a device with this name works, so your device is different from other with same name, wait for all-sollutions, he can explain you how to get raw data from the com port comunication, with this data we can clearly see whats going on with your device

try ask easun direct, looks like direct brand from him at the bottom its a hint that it work, its the only thing i found on search your device name with qpigs or qpiri (protocol comands)

@softwarecrash tx rx 12v gnd ??????? show-me wlki link please

avenseElectro avatar Oct 23 '24 18:10 avenseElectro

Your cable is for the wifi dongle. That's why you have also the 12v pin in that.

BTW: Can you please show us the complete wiring from your inverter to the Wemos? Perhaps there is a problem. We can not solve it, when we don't know your wiring.

show-me wlki link please

If my connection was wrong, the inverter I have that uses the pip30 wouldn't work either...
