Your Vue energy monitor depends on Wi-Fi to send measurement data to the Emporia cloud. This article covers what happens when your Vue loses its internet connection — what it still captures, what you lose, and how the app handles the reconnection.
Quick Summary
Under ~15 minutes offline: no data is lost. The Vue buffers measurements locally and uploads them when the connection returns.
Over ~15 minutes offline: measurements during the outage are averaged rather than stored at full resolution. You'll see total energy for the outage window but not the minute-by-minute detail.
The Vue itself keeps measuring — it just can't deliver that data to the cloud until Wi-Fi comes back.
Short-Term Network Interruptions (Under ~15 Minutes)
If your internet drops for a short time — a router reboot, a brief ISP outage, a Wi-Fi hiccup — the Vue has enough on-device memory to store all measurement data for the duration. When your connection is restored, the device uploads the buffered data automatically and your charts look the same as if nothing happened. You won't see a gap.
Extended Network Interruptions (Over ~15 Minutes)
If the outage lasts longer than about 15 minutes, the Vue continues measuring, but the buffered-data window is exceeded. When the device reconnects:
The Vue resumes normal real-time reporting.
The energy captured during the offline window is rolled up and reported as an average over the outage period.
Your total kWh for the day will still reflect the energy used during the outage — the shape of the curve just won't show the individual peaks and valleys for that window.
For most customers this is a non-event. If you're tracking a specific appliance during the outage window, though, the minute-by-minute detail won't be recoverable.
A note on offline accuracy. Measurements captured during an extended offline window aren't held to the same accuracy guarantees as live cloud-reported data. Treat them as a reasonable approximation rather than a precise reading.
Why a Consistent Connection Matters
For the most accurate, real-time view of your energy, keep your Vue on a stable 2.4 GHz Wi-Fi signal with reliable internet. If you notice frequent short outages:
Check signal strength at the panel location. Panel rooms are often on the edge of a home's Wi-Fi coverage.
Consider a Wi-Fi extender or mesh node closer to the panel if the signal is weak.
Confirm the Vue is on your 2.4 GHz network, not 5 GHz. The Vue does not connect to 5 GHz.
Vue Gen 2 and Gen 1
Older Vue generations (Vue: Gen 2 and Vue: Gen 1) have similar offline behavior to the Gen 3 described above — short outages are buffered, longer outages fall back to averaged data for the outage window.
What About Local Access?
The Vue is a cloud-based device and does not currently support direct local data access — meaning even when the device is on your local network but the internet is down, the Emporia app cannot read from the device directly. All data flows through the cloud. See How Your Vue Works for more on the cloud architecture.
