It worked and resetted itself now Can't detect device. I purchased these product last year winter. It worked well till last week. I don't know why the app reset everything and disconnect with devices. I haven't touched the app or the device after set up schedule. Now I try to connect with the app and devices but the app can't detect them. My wifi supports 2.4 . So annoying. Bought for my plants while I m away home . My plants didn't get enough light while I had trip.
