Wi-Fi
Svitgrid ED-1
Reads your inverter through the small Wi-Fi module already fitted to it. Nothing to wire — you plug it in and that is the install.
- See your system from anywhere, not only at home on your own Wi-Fi.
- History with no gaps, even overnight and with your phone switched off.
- Charge and discharge schedules run on their own, whether you are there or not.
Check that ED-1 will work before you buy. ED-1 reads the inverter through its Wi-Fi module, and some modules, including recent Deye ones, refuse every connection from your home network. Set up your station in the Svitgrid app with your phone as the collector: if the phone shows live readings, ED-1 will work too. How to check in 10 minutes. If the phone cannot read the inverter, choose ED-1.1 — it connects to the inverter by cable. See the list of supported inverters.

The app needs a paid plan. The price above buys the hardware; the subscription is separate and starts at $2/month. You buy the plan inside the Svitgrid app, not on this site — open Svitgrid on your phone and choose a plan there. See plans.
You do not have to buy hardware at all — Svitgrid can also collect from your phone or from a Home Assistant install. Compare the four ways to collect.
How it works
Your inverter already has a small Wi-Fi module on it — the one the installer fitted, the one that feeds your inverter manufacturer’s app. ED-1 joins the same home network and reads the inverter through it. You plug ED-1 into an ordinary USB charger somewhere near the inverter, and that is the whole installation.
Why bother, if the app already works
The Svitgrid app can read your inverter by itself — but only while your phone is at home on the same network. ED-1 runs all day and all night. That is what gives you readings while you are away, a history with no holes in it, and schedules that actually run on time.
