Issue with latency when triggering local HTTP POST requests from a mobile environment?

Hi everyone,
I’ve been trying to move more of my dashboard triggers from my PC to my iPhone, but I’ve hit a snag with the “Web Requestor” Edge driver. I’m attempting to set up a routine where an action in a mobile app triggers a local IP command to my SmartThings hub, but I’m experiencing significant execution lag (sometimes 3-5 seconds) before the lights actually respond.

As part of my testing, I’ve been using a delta mod on my mobile setup to see if I can run a background script that pings the hub’s local API more consistently. The idea was to bypass the cloud dependency for a “virtual button,” but it seems like the mobile OS might be throttling the network requests from the script.

Has anyone else noticed that iOS puts background automation into a low-power state that interferes with the Web Requestor’s responsiveness? I’m trying to figure out if I need to adjust the keep-alive heartbeat in the driver settings or if I should look into a different bridging program like Edgebridge to handle the incoming script triggers. I’d love to hear if any of you have successfully integrated a custom mobile script with your SmartThings routines without the annoying cloud delay. I really want to get this local execution as snappy as possible!
