A home energy monitor with no app and no subscription
A good home energy monitor for solar shows what your solar, your house, the grid and your battery are doing right now, without you opening an app. RayHub is a solar hub for your wall that does this. It reads your inverter over your home WiFi, needs no app or account, has no subscription, and keeps your readings in your home.
RayHub is in pre-production and pre-orders have not opened. Register your interest and we'll email you when they do.
What a home energy monitor shows
| Solar | How much power your panels are making right now. |
|---|---|
| House | How much power your home is using right now. |
| Grid | Whether you're sending power out or drawing it in. |
| Battery | Whether your battery is charging or discharging, and how full it is, if you have one. |
The usual options
Most homes with solar can pick from two kinds of monitor.
| Inverter apps | Many inverter brands offer their own app, which shows your system on your phone. You open the app to see your numbers. |
|---|---|
| Clamp-on monitors | These measure power with sensors that clip around the cables in your switchboard. Have a licensed electrician fit sensors inside your switchboard. |
What RayHub does
A solar hub for your wall that shows what your solar is doing right now.
| How it reads | It joins your home WiFi and reads your inverter over your home network. It asks your inverter for fresh readings every second. A few brands ask for a slower pace, and the hub follows it. |
|---|---|
| What you see | Live power for your solar, your house, the grid and your battery. You also see today's solar, export and import totals when your inverter provides them. |
| No app | You set it up on the hub's own touch display, or from your phone's browser. There's no app to install and no account to make. |
| No subscription | You buy the hub once. There's no cloud service and no subscription. |
| Your data | Your energy readings stay in your home, and your live numbers keep going if your internet drops out. |
| Power | It plugs in with USB-C and runs from a USB power supply. There's no wiring to do and you don't need an electrician. |
Every reading comes from your inverter's own data, so accuracy follows your inverter.
