Wireless PID Controller - Question

Hey guys,

I've seen a few RS485 modules that connect solar chargers to web interfaces via wifi, but I was wonderging if there are any avaialable wireless modules that use PID RS485 to communitcate via wifi and control temperature.

Essentially I want to control my PID temp controller over wifi with a simple interface - Suggestions?

Thanks so much for your input guys - its helping me learn a lot about this!
