See your eGauge meter on your iPhone
with Cenit · iPhone & iPad · free for a homeCenit reads your eGauge meter from the same link you open in your browser. See what your solar is making right now, how today compares to your best days, and what the panels are saving you.
Download on the App StoreAn eGauge isn't an inverter. It's a meter in your breaker panel with a clamp on each circuit, so it sees what your panels make whatever brand your inverter is. Cenit isn't made by eGauge Systems. It's an independent app that reads your meter and keeps what it reads on your phone. You don't make an account with me.
What you need
Your meter's link. It looks like egauge12345.egaug.es, and it's the address you open the meter at in a browser. If you don't have it, ask your installer.
The meter has to open without a password, and your installer has to have set up a register for solar.
How to connect it
- Download Cenit and open it. You can look around with example data first if you like.
- Tap Connect my inverter and pick eGauge from the list.
- Paste your meter's link and tap Connect.
- Have more than one meter? Paste all the links at once. Each one shows up as its own plant under Plants.
- That's it. The meter keeps its own history, so Cenit pulls in about a year of daily totals and 30 days of curves right away.
If the link opens in your browser without a password, it works in Cenit.
What you see from your eGauge
What your solar is making now and today
The watts right now and today's kWh, read from the meter's solar total. The meter records every minute, and while the app is open Cenit checks every five minutes.
Today against your best days
Drag your finger along today's curve to see what the panels were making at any moment, in five-minute steps. The dashed line behind it is the most they made at that time of day over the last 14 days. A sunny day that comes in under it means something changed.
What the panels save you
Tell it what you pay per kWh and what you get for power you send to the grid, and it works out about how much the panels saved you this month and this year, in your own currency. In the US it can fill in your state's average price. In Mexico you get your margin before CFE's DAC tariff instead.
Widgets and alerts
Today's numbers on your home screen. And a heads-up if the panels go quiet in daylight. The meter keeps answering even when the inverter stops, so Cenit can tell the two apart.
What you don't see
Your eGauge measures the whole solar circuit, not each panel. So Cenit can tell you production dropped, but not which panel. It also doesn't read your home's usage or the grid yet, even though the meter measures them.
Cenit and the eGauge page
Your meter has its own web page. Cenit doesn't replace it.
What you still use the meter's page for
Every circuit on its own, your home's usage and the grid, and any setting on the meter, like naming the clamps or turning on a password. Cenit only reads. It doesn't change anything on your meter.
What Cenit adds
A simple screen for today, your curve against your best 14 days, a savings number, widgets and alerts. Your history stays on your phone, so you can see it even when the meter is offline. And if another home runs an inverter cloud instead of a meter, it fits in the same app.
If you're an installer
Paste all your customers' links in one go. Each meter is its own plant, and Plants shows them together, with the ones that went quiet or don't answer. More for installers.
What it costs
For your home, nothing. Cenit is free for up to 3 plants and has no ads.
If you're an installer watching more plants, you pay by how many, once or by the month. 4 to 10 plants is 9.99 USD once or 0.99 USD a month. 11 to 49 is 39.99 USD or 3.99 USD a month. 50 or more is 74.99 USD or 7.99 USD a month. Paying once is for good. The first month after the app sees more than 3 plants, every plant is open.
Questions
Is there an app to see my eGauge meter on iPhone?
Yes. Cenit reads your eGauge from the same link you open in a browser and shows what your solar is making, your history and your savings. It's free for a home.
Does it matter what brand my inverter is?
No. Cenit reads the clamp on your solar circuit in the breaker panel, not the inverter. Any inverter works, as long as your installer set up a register for solar on the meter.
Can Cenit show my home's usage and the grid from the eGauge?
Not yet. Your meter measures them, but for now Cenit reads only the solar side. Savings use the kWh you type in for each month. The meter's own page shows usage and the grid today.
My meter asks for a password. Can Cenit read it?
Not yet. Cenit only reads meters that open without a password. Your installer can allow reading without one in the meter's settings, if you're fine with that.
Is Cenit made by eGauge?
No. Cenit is an independent app by Hrvoje Matošić, made in Mexico, and isn't made by or affiliated with eGauge Systems. It reads the meter through the same link you open in your browser. If eGauge changes something on their side, the connection can stop working for a while.
Cenit also works with NEP, Hoymiles, APsystems, Enphase, SolarEdge, Growatt, Huawei, Fronius, Victron and other inverter brands. See everything Cenit does.
