Trip an IP based Form C Relay

Extremely new to the forum and Roll20.  Has anyone tried tripping an IP based form c relay upon an event happening?  Is it possible? 

I hvae no idea what this means. What is an IP-based Form C Relay? It sounds like it is something external to roll20 itself, and Roll20 is explicitly set up to isolate itself from all external sources. My guess is you'd probably need to be able to write a browser extension.

Hi, so lets say a player enters into a specific room, I want to send a piece of code that trips a form c relay to trigger a fog machine or a light, etc.  Thank you for your time

I don't know what a "Form C Relay" is either. Could you elaborate?

sure, if you were going to automate something, like let's say your on vacation and you want to turn on your lights remotely from an app.  What is "under the hood" and controlling it is a relay.  I want to see if I could affect the physical world (fog machine, lighting for lighting, etc) when an event happens, like, entering a cave and the lights dim and fog machine starts.  Starting to sound like I have my answer.

Here is an example&nbsp; <a href="https://www.frightprops.com/triggerable-fog-machine-kit.html" rel="nofollow">https://www.frightprops.com/triggerable-fog-machine-kit.html</a>

I don't know how that has anything to do with Roll20. However, if you want to set up an event that will activate something in the game, that is possible with Mods (API scripts) but it will probably require someone to write one for you. I would suggest asking about it in the Mods (API scripts) forum.&nbsp; State what you want it to do, be specific. And I suggest not using examples people won't understand.&nbsp; Example of a specific request: I would like an API script that activates an FX effect when the players reach a certain location on the map.&nbsp; Note: API access is a Pro (paid) feature.&nbsp; Edit: if you want something where an event in the game triggers a thing out of the game, that is outside the scope of the forums here. And as stated earlier, probably would require an extension.&nbsp;

OK thank you

To gop back to my earlier point: you seem to be asking if something inside roll20 can operate something outside of roll20. The answer to that is a firm no. You would need to build another piece of softwrae (like a browser extension) to check what is happening in Roll20 and transmit it to where you want to go.
