Replace AUBE telephone controller w/ WiFi controller

Azzuri

Good morning,

I am looking to replace a pre-exisiting AUBE telephone controller:

With something that is WiFi controlled but essentially, does the exact same job. Which is to set the boiler's controller (which is a Tekmar) to occupied or un-occupied.

Of course I've done the google searches, but am having a really hard time to find something that meets my description. I have to think that there is something like this available somewhere. Perhaps, I am not looking in the right place.

Would anyone here have any suggestions or recommendations? Appreciate the help in advance. Thank you
