Salus SQ600(WB) - Device Handler


Im brand new to the Smartthings platform and am looking for some knowledge around device handlers…

I have recently installed 7x Salus SQ600(WB) thermostats in my house but have to have them running off a separate app for this to work remotely. I understand that if I can find a device handler then I can create a device type for them. There is very little info online about the Salus brand and so my question is does anyone here know where I could find the device handler for this product?
