After having a bit of a close call with a missed oil delivery to a vacation home this winter, I decided to find a way to monitor fuel oil levels remotely. There aren’t many devices out there to do that, but I did find the Rollie WTG-BT tank gauge. It is WiFi-enabled, reports oil levels back to a portal, and sends alerts via SMS and email. It all works perfectly well, but I wanted to ST enable it! The DTH I built is available here;
It provides current oil level and some basic usage information. Hope folks find it useful!
