Under fermentation tab in your “Brew” session at Brewers Friend, you can choose from 1 of 3 hydrometers, and one of those is the Tilt. Just select Tilt hydrometer and the color, and as the page indicates, it’ll take up to 5 minutes to connect. You’ll have to copy the link when you choose which hydrometer, to paste on the Tilt app so the app knows where to send the info to. You’ll need to have a phone with the Tilt app within range of the hydrometer so it can receive the info from the Tilt and publish it the link to the Brewers friend fermentation page. I am using an old iPhone that I installed the app on and just leave the phone next to the fermenter.
Ps. I have better luck with the Tilt app, than I do with the Tilt 2 app.
Pss. I hope the developers here will someday make it a standalone feature as I don’t use the “Brew” feature that often.
