Now that almost all indoor lights in my house are smart, I am thinking about the lights and sensors in my porch. As winters can be cold here, down to -25C on a few days last winter for example, I find it hard to find smart outdoor lights that can operate at cold temperatures. I would prefer build-in down-lights, so any GU10 smart bulb that can handle cold winters is probably fine too. Voltage here is 230V (Europe). I have seen that Philips Hue has a GU10 that works down to -20C, but that is for US only (120V), so not an option for me. If you have found a good solution for this, please share.
For outdoor sensors I found the Philips Motion sensors | Philips Hue, which is speced down to -20C, so that is an acceptable sensor for me.
While I’m sure something exists, I’ve never found it. I instead decided to just settle on normal lighting that is controlled with automation at the source of the power rather than the luxury of having each light controllable (which I could still do by tapping into each light before it hits the main power line). There is so little to choose from and the stuff that does claim to work is not from really reliable vendors (that I’ve found) and it’s too much risk for me. And, honestly, the only thing I wanted was to have color soffit lights, and nothing looked like it would stand the test of time.
I found that the Philips 230V GU10 – smart spotlight also is specified to work down to -20C. Which makes this a good candidate for me. All three versions; the white, the color temperature version and the color version are all listed as -20 °C … 45 °C
