Another Product that Works with Twine
As an early user of Twine for a project that I was developing, I'm offering those that have Twines a free upgrade for your Twine. My product is a HVAC filter monitor which you can read more about on our website (www.airflow1.com). The CFM-GM Clogged Filter Monitor has an option to connect directly to the breakout board for Twine, you then set rules to send yourself a text message when the switch closes to check your air filter.
I've had this running now for over a year and it works great!
Sorry for informing everyone about it here and on other discussion channels but hope you take the time to at least see what else the Twine can do!
