Don’t you have an old unused iPad? I’m using a NodeRed customizable dashboard comunicating over MQTT with Homey running on a old iPad 2 (not the air2) with iOS 9:
Well, not only will a KOBO Aura be cheaper than an Android tablet even of average quality, but in fact the problem is not there: the issue is the autonomy of the tablet. If you have a power supply right behind the tablet on the wall and you can hide the cables, that’s fine, but it’s quite rare… Where an e-ink tablet will have an autonomy of several weeks, an Android tablet with a screen that’s always on will have a much lower autonomy, even during the day, and not much more if the screen is off. That’s the real thinking
Thanks for mentioning this to me… Just started to play with it and love it. DId not buy a tablet yet, currently trying it out on my “normal” iPad Pro still.
