I have a Philips 49pus7101/12 from March 2016 and can tell you that Jointspace will not work on this model on port 1925 , i also think some later models?!
But in the past i have searched for other methods to control the TV and found some interesting stuff.
Before i had Homey i did some testing with Openhab on an RaspPi.
Below is a copy of some thing i have founded and tested.
I found on website https://github.com/suborb/philips_android_tv some python code.
With this code the controls works.
First you need to us the command pair to pair the TV with the server, when you do this the TV generates a code that you need to enter in the python code…
When that is done, a new user and pass is shown and with this user and pass you can conrol you TV.
Some notes from site
The API is roughly the same as JointSpace (http://jointspace.sourceforge.net/ ) with the following differences:
-Uses HTTPS over port 1926
-Uses /6/ instead of /1/ as the API path
-All calls have to have digest auth to be successful
-An initial pairing to determine the user/pass is required
-Channel and Source methods aren’t available
-Channel status and changes are performed using a different protocol that isn’t described here.
The tool here will do the initial pairing. The credentials can then be used in a standard way (digest) in other tools

Maybe this will help in futher development in a working Homey App for the new models ( Without IR)
