Not sure why they don't include the feet with the Wi-Fi models but these feet are exactly the same same the feet on the Non-Wi-Fi model and work for both Wi-Fi and Non-WiFi models.
Feet For WALL UNIT (not compatible with WIFI model)
They should just come with the heaters
Feet work with wifi wall unit. Obviously cannot mount to the wall. Connected easily and set on the floor in the guest bathroom. Third HeatStorm wifi unit purchased.
Worked just fine with my Wifi Version Unit that was supposed to be wall mount. I did not have to modify the Wifi unit at all, I just had to unscrew the existing mounting leg and then just mounted these feet with the screws that came in the feet order. Easy deal, took 3 minutes.
I'm puzzled as to why they list this as something that doesn't work with the Wifi unit...
