Compiling

It would be nice if you can update the code to work with the new board database and the SoftwareSerial that is included. Now we get build errors.

Your Github is linked by homeassistant so would be nice to have an up to date code.
Im by no name a programmer and can not fix the problem on my own.
A list of the used github / libraries (including the makers) would be nice

I used arduino 1.8.10
Board Manager from https://arduino.esp8266.com/stable/package_esp8266com_index.json

Hey @hidra000,

I havent updated my esp8266 for a while as I recently moved and I haven't had the time to reinstall the board on my meter, but In a few weeks I'll have a look at it.....

I've just fixed the SoftwareSerial object declaration in my fork and PR'd that #4

What is your issue with the board database? I'm current using the latest (2.6.3) and also tried one from the time of your post and both work fine.
