I wasn’t aware that Athom updated their own app. Sadly, it still uses only infrared to turn the TV on, which is not an option for me. Since I don’t feel like waiting for Athom to ever implement this I will continue developing my own app. So to use the ‘on’ feature of my app your tv needs be connect via cable. As stated before, I might add IR support in the feature.
My apologies for being a bit absent lately, you know, holidays, work, and live in general… A quick little update on my side, as of today (not you pushed to Github yet) I have my TV status working solid! Side note, I put a delay of at least 2 minutes before polling for the current state of the tv. This seemed to do the trick for me locally. This means there is a delay before Homey has the latest state of your tv if you turned it on/off via remote. On/off inside Homey and it is pretty much instant.
To make things even better, I finally got the freaking on/off triggers working! So I will probably release a beta version of my app on GitHub in the next month or so. Got to polish some stuff and maybe add some extra triggers for the first release.
