I used a wired Aeotec 6 in 1 sensor as an outdoor Luminance sensor, so various automations work when it gets darker… it worked perfectly, then it died and after months, I managed “to fix it” now it died properly. I only need the Luminance sensor as I have a weather station etc…
I use a BH1750 connected to an ESP8266 running esphome. All housed in a waterproof (IP68) clear polycarbonate box.
I was going to mount it on the roof but found that it works perfectly well on one of my northern windowsills (I’m in the southern hemisphere). So in my case the box did not end up having to be waterproof.
