SPAN Home On-Premise

  • Updated

What is SPAN Home On-Premise?

SPAN Home On-premise is a web-based backup access path to your SPAN Panel. It’s designed to give you greater local control and peace of mind. If there is an issue that disrupts your SPAN Panel’s connection to the internet and ability to use the SPAN Home App, you can use SPAN Home On-premise to manage your power, toggle circuits, and adjust backup priorities.

How does it work?

SPAN Home On-premise communicates directly over your home’s Wi-Fi network or through the Panel’s own local Wi-Fi. This web app allows you to:

  • Monitor Power Flow: See real-time energy data for your whole home.
  • Manage Circuits: Toggle individual relays on or off.
  • Adjust Backup Priorities: Update which circuits stay on during an outage (Must Have, Nice to Have, or Non-essential).
  • Override Grid Status: In emergency scenarios where communication with your battery (like a Tesla Powerwall) is lost, you can manually tell the panel whether to act as if it's on or off the grid.

Who can use it?

Currently, this feature is available for homeowners with a SPAN Panel MAIN 32. However, we hope to have the feature available to all homeowners in the second half of 2026. 

If you are unsure which panel you have, check out this article: How do I know which SPAN Panel I own?

How Secure is SPAN Home On-Premise?

A key component of the feature is that all access is local only, meaning that it operates entirely on the home LAN and does not use cloud connectivity. Furthermore, SPAN Home On-premise access requires authentication and access is limited to devices on the local network, with credentials managed directly by the panel. This is an important security choice because it means that someone with malicious intent would have to be inside or in very close proximity to your home and have either your home WiFi network name and password or an ethernet cable connected to your LAN in order to make changes to your panel. All of these choices limit access to keep your home energy data, settings, and breaker controls safe and private.
