Solis, zappi and Octopus setup checklist

A Solis, zappi and Octopus home can be powerful, but only if the setup points to the same real property.

This checklist is for homeowners and installers preparing a supported home for 1app.energy. It keeps the setup simple: connect the right accounts, check the first values, and leave control off until the device and tariff data are verified.

The quick version

Before you connect the home, gather:

• the SolisCloud account for the correct plant;
• SolisCloud API details if API-key setup is needed;
• the myenergi account that owns the zappi;
• the zappi gateway serial number and API key;
• the Octopus account number and API key;
• a simple note of the home topology: solar, battery, EV charger, grid meter and CT clamps.

The main rule is simple:

A sign-in or API key is not the setup. The setup is verified when each source describes the same home.

1. Check the home topology

Write down what the home actually has:

• solar panels;
• Solis inverter;
• battery;
• zappi charger;
• external solar or another inverter;
• CT clamps and what each one measures;
• single-phase or three-phase supply.

This stops 1app.energy showing equipment that is not there, double-counting solar, or treating EV charging as ordinary home use.

If you are unsure about zappi CTs, read zappi CT mapping in a solar battery home.

2. Connect Solis

Solis provides the inverter, solar, battery and grid context where the installation exposes it.

Before connecting, check:

• the SolisCloud account can see the correct plant;
• the inverter serial number matches the home;
• API Management is ready if you are using API-key setup.

Use how to get your SolisCloud API key if you need the Key ID and Secret.

After connection, check that battery percentage, grid import/export and solar generation look believable compared with the real home.

3. Connect Octopus

Octopus gives tariff and meter context where the account supports it.

Before connecting, check:

• the account number belongs to this property;
• the API key is from the same account;
• the home has an active electricity supply;
• smart-tariff slots are treated as Octopus schedule evidence, not physical proof by themselves.

Use how to get your Octopus Energy API key and account number if you need the connection steps.

If you are not on Octopus, use manual tariff setup where available instead of guessing another customer's tariff.

4. Connect zappi

zappi matters because EV charging can be one of the largest loads in the home.

Before connecting, check:

• the myenergi account owns the charger;
• the gateway serial number is correct;
• the API key was copied from the gateway device;
• the charger belongs to this property.

Use how to get your myenergi API key for zappi and eddi for the myenergi steps.

After connection, check that EV charging appears only when the charger or car is actually drawing power.

5. Check one normal day

After setup, use one normal day as the first sanity check.

Look for:

• solar during daylight;
• battery charging and discharging at believable times;
• grid import when the home has a large load or low battery;
• export only when generation or discharge exceeds demand;
• EV charging matching the real charging session;
• tariff periods matching the customer account or manual tariff.

The goal is not to inspect every watt. The goal is to catch obvious mismatches before the dashboard is used for decisions.

Common setup mistakes

What installers should hand over

For a clean 1app.energy setup, hand over:

• SolisCloud login route and plant name;
• inverter serial number;
• whether API Management is activated;
• myenergi account owner;
• zappi gateway serial number;
• CT clamp notes;
• Octopus account number and tariff name;
• any known export tariff or manual tariff periods.

That is usually more useful than giving the customer another long list of apps.

Common questions

Do I need Solis, zappi and Octopus to use 1app.energy?

No. The value depends on the supported devices and tariff setup in the home. Solis, zappi and Octopus together give strong inverter, EV and tariff context when all three are present.

Should smart control be enabled straight away?

Usually no. First connect the right sources and check one normal day. Then enable supported smart control only where the customer wants it and the installation allows it.

Why does zappi matter if Solis shows home load?

EV charging can dominate home demand. zappi context helps 1app.energy understand when a big load is the car, not normal household use. That matters for battery behaviour and tariff timing.

What if I am not on Octopus?

Use manual tariff setup where available. Do not guess rates, off-peak windows or export prices.

Final thought

The setup is right when Solis, zappi, Octopus and the home topology all point to the same property.
