welll........ devils advocate.. i could see the wifi being used so the device can be incorporated into the home automation system [climate control]. its not about dehumidifying, its solely about engaging the dehumidifying as needed.
To steel-man the argument some more, if you have variable-rate electricity, it could turn on when electricity is cheap.
This can be done with something like Zigbee. Or even simpler: you hook a non-connected device up to a "smart" power socket. No need for the device itself to talk to the outside world.
The solution to too many unnecessarily-connected devices is more connected devices?
Now you're getting it!
The solution is not more but different connected devices so I can decide for myself what needs to be connected and by which protocol. Get the dumbest device on the market, no wifi, no internal clock, maybe not even a humidity sensor and then, if and only if I need to remote control it, for example to put it on a schedule, I can use the cheapest "smart" device on the market to connect it to an in-house machine that can turn it on and off.
ZigBee is Bluetooth, so controls can be done entirely locally.
We have Aqara (ZigBee) water leak detectors for our sink and basement, a 3rd party USB ZigBee dongle and a raspberry pi running home assistant. This gives me a discount on our home insurance that is more than the devices. Everything runs only locally.
(Admittedly I am not including the cost of the pi, but you could salvage an old laptop or something instead. My pi has other things on it other than HA, its multipurpose)
I also have some WiFi RGB bulbs/led. Using home assistant I can swap their colors for the holidays and I never have to decorate again. I'm lazy, and I hate Christmas.
