HabPanel Viewer or Fully Kiosk Browser can wake on proximity, but the reliability depends on the device you’re using. I have a tablet that lives next to my couch, so that it’s within reach whenever I want to be lazy and control something without getting up. I don’t have HPV on it, but it’s easy enough to open openHAB.
I’m a little wary of the compatibility being limited to Sonoff and eWeLink devices at release (with Philips promised for the future). However, wanted to note for you that work is being done on a binding for these devices. Maybe it’ll be possible to add this device in the future.
