The bridge between Gladys and the thousands of IFTTT services, via the IFTTT Webhooks service. All you need is the Webhooks key from your account.
What it brings: two scene actions, “Trigger an IFTTT event” (name + three values) and its JSON variant, to launch any applet from a scene; and, with Gladys Plus, the trigger “IFTTT event received”: an IFTTT applet calls the webhook relayed by Gladys Plus and launches a scene, with the values in variables. An “IFTTT Button” widget puts an applet on the dashboard (confirmation possible).
Limitations: the IFTTT → Gladys direction requires Gladys Plus (the URL is relayed by Plus). The incoming URL is a secret; an optional shared secret enhances control. A free IFTTT account limits the number of applets, not the number of events.
