I'm considering replacing my outside light switch timers that turn the lights on and off at the same time every day year round. They're very frustrating to work with. I have found similar switches that do follow the solar calendar but there's no W-Fi or app.

So someone told me about Kasa switches. The website is very evasive about setting the system to turn the lights on and off according to the solar calendar. Do they do that? And how do you set it up in the app?

Also, are there different models for single pole and 3-pole installations? Yes there's a white wire in the boxes. This would be a straight replacement.

TIA
