If you do not see a blue bar with information about LAN mode in the ewelink app when you enter the device tab, it means that the device is not reachable in LAN for some reason.
A separate issue is whether the schedule works on the device without a Wi-Fi network. Scenes definitely don’t work then!
As for your devices, I can’t say whether they can behave similarly to the S26R2 and Micro.
Make sure you have the latest firmware and LAN mode enabled in the options of all devices. And test… Of course, there is an option that they may not work this way, and they certainly will not work after a power reset.
