Physical Thermostat options for wireless heater

So I’m looking to buy some electric convection wall heater panels. Either an Amaze Heater or something like it. Link here ==> Amaze Solo 400 Watt (Smart)

I looked closely online and it’s basically a Sonoff wired up to the back. So I can save a few bucks and get my own device to control it.

But what can I get in terms of physical thermostat on the wall to control it? It will be on the other side of the room so it needs to be wifi/zigbee/zwave.

Ideally, it just needs a temperature sensor, readout of the current temp, and buttons to change the temperature up or down.

For example, these are what I currently have to control the not smart baseboard boiler system. Wired Thermostat Heat Only
