Need some help with finding a way to control turning my 2x 240v 1500W wall heaters (dimplex TWH1531CW) on/off from my phone and Google home. Currently they are connected to a line voltage single pole thermostat (stelpro swt1) and a programmable 120v wall switch (not sure why the electrician used a few 120v switch). I would like to be able to change that switch or/and something behind it so that the hearers could be turned on/off with my phone and Google home - don’t really need to control temperature. A lot of the switches I looked at don’t do such high power, was wondering if there was something out there oraybe I could use something in between to handle the power.
Any help would be appreciated, thanks in advance.
