SonOff pow R2 - Unable to compile 1.13.4

[AlbertWeterings]

When compiling for SonOff POW R2 I get this error:
`sensor:106: error: 'T' has not been declared

void _sensorWebSocketMagnitudes(JsonObject& root, T prefix) {

                                               ^

exit status 1
'T' has not been declared`

It compiles fine for me, both on PlatformIO and Arduino IDE 1.8.6 under Linux.
Notice T is a templated variable defined just one line before... maybe your IDE/OS is not getting that, try removing the line break:

template<typename T> void _sensorWebSocketMagnitudes(JsonObject& root, T prefix) {

[AlbertWeterings]

removing the line break is fixing the issue in Windows Arduino IDE.

@AlbertWeterings do you have git with autocrlf=true? may be related to #1205
check ~/.gitconfig, if it has this:

[core]
    autocrlf = true

.gitattributes to the rescue, *.ino text eol=lf && *.h text eol=lf should override autocrlf settings for users. but i need to check how it will behave with *.gz.h beforehand

I don't use git, i just download the repository as zip and open it Arduino IDE on Windows.

That's strange. I can build it using Arduino IDE 1.8.8, from Windows Store.
I tried downloading espurna-dev.zip but it does not convert line endings for Windows crfl, so not that either. Hm.

[AlbertWeterings]

I'm at Arduino IDE 1.8.5, for Windows there might be the difference
