Deye in Home Assistant? This may already be done for you
The wish makes sense: see your station, know about outages, set everything up your way. We started the same way, and Svitgrid grew out of exactly that. Home Assistant is a great tool. But if you need a station and not one more server, first look at how much time the path takes and what is already done.
What it takes to see Deye in Home Assistant
| Step | What it involves | Approximate time |
|---|---|---|
| Server | Buy a Raspberry Pi or a mini PC, write Home Assistant OS to it, and find it a place that survives an outage | 1–3 h |
| Integration | Install HACS, then the Solarman integration, and find the definition for your exact Deye model | 1–2 h |
| Numbers | Check the signs of battery and grid power, and set up the Energy dashboard | 1–2 h |
| Power alerts | Write an automation and install the companion app | ~1 h |
| Access from outside the home | A Nabu Casa subscription, Tailscale, or port forwarding | ~1 h |
| Night tariff | An automation that writes to the Deye time-slot registers. A mistake here means an inverter that does not charge | an evening |
| After that | HA and integration updates, backups, and checking that everything works after them | ongoing |
| Total | 6–10 h |
A first result in a weekend, if everything goes well.
You wanted automation? Here is what already exists, without a line of code
Draw it, and it runs
Select a period on the day chart and choose an action: charge from the grid, hold the charge, or generator. Svitgrid writes it to the inverter and restores your settings afterward.
The water heater turns on by itself
Zigbee sockets and relays through the gateway: turn the water heater on when the battery is above 80%, and off during a scheduled outage.
Night tariff
23:00–07:00: charging from the grid at half price. Both Deye switches turn on together.
The alerts you would write yourself
Power went out, power came back. They reach your phone and, on the Plus plan, the people you share your home with.
Most people install Home Assistant for these four things.
The same result in 10 minutes
Home Assistant
- 6–10 hours to start
- A server at approximately 3–5 thousand ₴
- Maintenance is yours
- New Deye loggers (serial starting with 26) cannot be read
ED-1
- 10 minutes: a USB charger and Bluetooth
- 999 ₴ and from $2 a month; the day planner comes with the Plus plan
- Updates itself, and rolls back a failed update by itself
- New loggers: ED-1.1 over a cable
Outage alerts, history, forecast, night tariff, and access from anywhere are there from the start, without a line of YAML.
Already running Home Assistant?
Then half of the work is done. The Svitgrid integration takes the Deye sensors already in your HA and passes them to the app: alerts, history, forecast, and the green tariff without a separate device.
Questions
Home Assistant does not see my new Deye. Why?
Loggers with a serial number starting with 26 give no data to your home network, so the Solarman integration cannot read them. An RS-485 cable helps: the ED-1.1 or a homemade ESPHome build.
Can I have both Home Assistant and the ED-1?
Yes. The ED-1 collects data for the app, and HA stays for your automation.
Try it before you build
You can return the gateway within 14 days. If Svitgrid does not suit you, you lose an evening, not a month.
