Agreed. Having to set up a raspberry pi or some other microcontroller is time consuming and the end product is ugly. I would like something small that connects to WiFi that operates off battery or could be plugged in permanently.

I recently purchased Wyze's sensor starter kit and have been quite impressed. The contactless sensors are tiny and have decent range to the corresponding bridge. Now Wyze just needs a documented, public API.

Pimoroni made this quite easy though if you know a bit of python https://shop.pimoroni.com/products/enviro-plus

Small and WiFi sound like an ESP8266 could be right for you. Or a Wemos D1 Mini, which uses an ESP but comes with a USB port.
