I got a NodeMCU ESP8266 12F (I paid a 12e but idk) and tried to upload some code for my SDM120M meter to it, the upload finally worked, but (i deactivated the software wdt) the hardware wdt keeps resetting the ESP after around 8 to 12 seconds (I measured it). I post the code under this text, there are tons of ESP.wdtFeed() in it but it isnt working.
The error I get in the console: ets Jan 8 2013,rst cause:4, boot mode:(3,2)
Followed by standart load xyz stuff and some cryptic characters.
