This was my first thought. In my case, I'm using an ESP8266 wired to a lux sensor and a motion sensor. I wrote some really basic code to poll the sensors and send the data via MQTT to my home-assistant.io container. HASS seemed like the logical choice given the disparate Z-Wave, Zigbee, Hue etc. devices in my home. The only challenge I didn't solve in the ESP8266 code is monitoring of its power supply (rechargeable AAs). I even 3D printed a decent-enough enclosure for the device. It looks kind of like a Dalek and a hockey puck had an unwanted lovechild.
