Benefits & Value

  • Sub-meter the geothermal system energy consumption separately from the total electric bill
  • Receive email/text alerts before a problem occurs
  • If an alert is received, check and troubleshoot the system remotely, no tools required
  • Alerts can be assigned a priority value, with specific people receiving specific alerts
  • Check system performance remotely at regular intervals (virtual PMI’s)
  • View multiple system parameters simultaneously in real-time
  • If no heating or cooling, check for inputs and outputs remotely
  • Avoid nuisance or unnecessary service calls due to user error
  • Troubleshoot remotely, then have the correct parts for the service call, no return trips
  • On-site service calls require no tools, just a smartphone with Internet access
  • Start-up and commissioning requires no tools, just a smartphone with Internet access
  • Heat pump manufacturer technical support staff can view the data to assist with troubleshooting
  • Refute high bill complaints
  • No proprietary hardware or software is required, just a smartphone with browser app
  • Solar PV arrays and net zero homes can be monitored and will display net energy in rich, colorful graphs
  • Sub-meter other household loads – water heater, circuit loads, mains, etc.
  • No monthly subscriptions or hosting fees
  • Compatible with any brand of geothermal heat pump
  • Compatible with any type of geothermal heat pump – water-to-air, water-to-water, split, combination
  • Compatible with three-phase units
  • Compatible with conventional air conditioners and air source heat pumps
  • No WiFi required
  • No ethernet required
  • No setup required
  • Stores six years of data, at which time the data can be downloaded and saved, then start another six years
