I wish I could help you, but my experience is with a USB serial adapter communicating with the panel. My experience ends at the text in the product manuals for the WiFi devices. I expect Dave or someone else will eventually show up and offer some suggestions.
The best thing I can tell you is to be mindful of what logic voltage levels appear at your panel versus your interface (whether it’s a WiFi-to-serial converter or a USB adapter). If they are different, the proper solution is to use a logic level translator. I have described this on the original forum page for Dave’s integration in several posts starting at this one:

There are several other posts regarding getting the WiFi-to-serial devices to work properly. The additional detail may be useful. Just scroll through the posts and you’ll see them.
Good luck.
