Hi there,
after some work, I finally managed to have a working and reliable wireless remote for my HA installation, using a 15€ Bluetooth keyboard.
Here’s how it looks:
I used the Keyboard Remote component (unfortunately it works under Linux only) and, with a huge help from some HA members, I managed to modify the code and solve a few problems that arose from using a battery powered device. Now the component works beautifully (it’s still in dev branch, sooner or later it will be out, I guess).
Of course, through automation you can control virtually anything, plus I added some voice feedback through Google TTS. But maybe my family members are the happiest: they practically don’t have to use their phones anymore.
If you have any question, I will be happy to answer them if I can.
