Got an email from IFTTT this morning:
On August 31, 2019, Nest will be retiring its Works with Nest program. In turn, Nest services on IFTTT will no longer work due to this change.
This SUCKS. I have a Nest Thermostat (Gen 3), Wyze cameras (v2), Blink cameras, and a SimpliSafe security system. It's all held together very tenuously by IFTTT and Works with Nest. Home/Away on the Nest is synced with Home/Away security modes on SimpliSafe. I'm not sure how that integrates on the back end, but I highly suspect that support for that feature will disappear. Home/Away on the nest triggers Motion Detection ON (or OFF) mode for my Wyze and Blink cameras via an IFTTT trigger. I also have Homebridge set up to control my Nest Thermostat via Siri.
Without Works with Nest, I'm going to have to rethink my entire strategy. For more information on the upcoming change from Nest/Google, check out their announcement.
