At last! After two years of begging Ifttt has now restored the “details“ of a service without requiring that you login to an account with that service. So you can see what triggers and actions are available before you buy a device.
Go to the service page, then choose details.
If the next page doesn’t list any triggers, there aren’t any. But if there are, they will be listed. Three sections: triggers, queries, and actions.
This is really important information because just “works with Ifttt“ doesn’t always tell you very much.
