First off, this little gadget is a game-changer! I've been using it for my homebrewing setup, and the WiFi feature is just *chef's kiss*. Being able to adjust temps from my couch while binge-watching shows? Yes, please.

The dual relay outputs work like a charm—no more babysitting my fermentation fridge. It seamlessly switches between heating and cooling based on my preset temps. Though, heads up: if you tweak settings mid-process, it'll aggressively correct the temp immediately (kinda overeager, but it chills out once stabilized).

The app? Simple and reliable. Pairing was a breeze, though I wish it logged temps every minute instead of 15-minute intervals (I’m nosy like that). Also, Google Home integration is basically decorative—stick to the Inkbird/Tuya apps.

Minor gripes aside, this is the only controller I’ve found that juggles WiFi + dual-stage control so well. 4.5/5 stars—would’ve been perfect with a longer probe wire and finer logging options!
