Extending from this Reddit thread and linked artcle, I found updated information on the TP-Link API and how to use it. I only have used it with my single smart bulb, but it might be helpful for other TP-Link products. The guide should be intermediate level, but it contains a lot of verbiage; just expect to tinker a bit. It took me a while to figure this out from scratch, but it shouldn't take longer than 30 minutes to your first applet.
Tools Used:
- Android Phone (to capture packets without jailbreak or another device to intercept, I've not looked for other platforms' apps)
- Kasa App
- Packet Capture
- IFTTT Webhooks
