I’m without my smartphone for a few days after it had a close encounter with some tarmac. I’ve lost a few superpowers: the ability to use Whatsapp and online banking. Most annoyingly I miss the ability to switch the lights on and off in my kitchen.
That’s only the case because we were using flic buttons to do it via Bluetooth (after another domestic mishap in which we lost our light switch). I’d recommend flic - the only “internet buttons” I know of other than the Amazon IoT button (unavailable in the UK currently) that are actually sufficiently versatile to call an arbitrary webhook.
