In a nutshell, it’s a $2.50 ESP8266 NodeMCU and a $3.50 flow meter … about $15 in parts total with a $1.50 custom PCB and fancy water-resistant packaging (including shipping from Alibaba, AliExpress and JLCPCB).
@mikey was kind enough to give me access to the Taplist.io API Beta on January 23, 2019. It took me about a day to integrate my keg monitor. I agree with @mikey … given the current state of the Taplist.io API, it shouldn’t take Plaato more than an hour.
The screenshots of my KegMonster.io smartphone / tablet app reflect an early beta. I’ve since added support for,
- One-Click Tweet Newly Tapped Beverage - Send a tweet with a detailed description (from Taplist.io) of a newly tapped beverage simply by clicking a button
- Low-Volume E-mail, Text and Smartphone / Tablet Notifications - Receive an E-mail, Text and / or pop-up notification on your smartphone / tablet when a keg reaches a configurable low-volume threshold
- Chart Live and Historical Pour Size and Keg Volume Data
- Export Historical Data - Configure and customize data reports in CSV format
Of course, you don’t need a fancy IoT platform and smartphone / tablet app to integrate your homegrown keg monitor with Taplist.io. You can simply hardcode your local wi-fi network name (SSID), password (if any), Taplist.io auth token and tap number in your wi-fi microcontroller firmware. As @mikey (and Ron Popeil) likes to say, “Set it and forget it.”
