Heating Oil FAQs

For WiFi  heating oil monitors, the monitor securely connects to the homeowners Wifi in order to send out the daily tank readings.

For 4G LTE heating oil monitors, our monitor securely connects to AT&T to send out the daily tank readings.

Our monitor works on a 4G network and our default carrier is AT&T with T-Mobile as the back-up. AT&T’s network coverage can be found at https://www.att.com/maps/wireless-coverage.html. We also offer a radio frequency (RF) monitor that comes with a receiver that plugs into any internet router. The RF signal can travel up to ¼ mile.

The monitor can be screwed into a spare hole in the homeowner’s heating oil tank.

The monitors are capable of being installed in less than 10 minutes. Your installer will utilize the free GREMLIN Dealer smartphone app to assign the monitor to a customer and tank and activate the monitor.

Each GREMLIN comes with an industrial Lithium battery that will last 7 years with one transmission a day. The battery life can be extended by configuring the monitors to report less often. For instance, the monitor can be triggered to report only after the level reaches 50%. Batteries are replaceable by the dealer.

Alerts can be sent to the appropriate person(s) in the company and can be viewed in the GREMLIN Dealer Portal. In addition, tank level readings are pushed into the dealer BOS each night.
