LG TV LB652v


I have a LG TV purchased on 2015 with model number LB652v. I guess it is a 2014 model.
Its firmware version is 5.5.35 and it says it has webos 1.4.x

There are many android apps which can control it. I assume it could be controlled through ST with a correct http call. Is there anything ready ? if not, from where should I start ?

is there a place where I could find info about LG webos api ?
