How to reconnect your Eddi to WiFi
Reconnecting your myenergi Eddi to your home network
If your myenergi app shows a light blue triangle on the Eddi tile, or a banner at the top saying a device is disconnected, your Eddi has lost its WiFi connection. Don't worry, this is usually straightforward to fix. This guide walks you through the full process, from preparing your phone to reconnecting your Eddi to your home WiFi.
The Eddi is the myenergi device that diverts surplus solar power to heat your hot water. If it loses its WiFi connection, it will still keep heating water. It is only the app reporting that stops, so there is no harm in taking your time with the steps below.
Your Solis inverter will usually still show as online in SolisCloud, the Solis monitoring app, and that is expected. The inverter and the Eddi use completely separate monitoring platforms.
Menu options on your Eddi may vary by model. The steps in this guide describe one common path, but your unit may use slightly different wording or menu layouts to reach the same settings.
How to tell the Eddi is disconnected
Two indicators in the myenergi app confirm the Eddi has lost its network connection:
A light blue warning triangle appears on the Eddi device tile in the myenergi app, indicating the device cannot be reached over the network.
A banner appears at the top of the myenergi app explicitly stating that a device is disconnected from the network.
Before beginning the WiFi setup, check that the time, date, and time zone on the Eddi's physical display are correct. Incorrect time settings are one of the most common reasons the setup fails.
Step 1: Prepare your smartphone
These steps prevent your phone from dropping the Eddi's temporary network during setup:
Turn Mobile Data off temporarily. This stops the phone from automatically dropping the Eddi's network to hunt for a 4G/5G signal.
Disable any active VPNs before starting the process, as they can interfere with the connection to the Eddi's local network.
Go to your iPhone's WiFi settings and turn off Private Wi-Fi Address before connecting to the Eddi's network.
Step 2: Activate the Eddi's access point
On the physical Eddi unit, you will turn on its built-in access point. An access point is a temporary WiFi network that the Eddi creates itself, so your phone can connect to it directly:
- Press the menu button (X) on the Eddi unit.
- Navigate to Other Settings > Internet > Wi-Fi > Wi-Fi Config.
- Confirm both Wi-Fi and Access Point are set to ON.
- The Eddi's screen will display a temporary WiFi network name (e.g. myenergi-XXXX) and a passcode. Write these down or take a photo, as you will need them in the next step.
Step 3: Connect your phone to the Eddi
In this step, you connect your phone directly to the Eddi's own temporary WiFi network, not your home WiFi. Look at the Eddi's screen for the network name and passcode it is displaying.
Open your phone's WiFi settings. Look for a network matching the name shown on the Eddi's screen (e.g. myenergi-XXXX). Tap to select it.
Enter the passcode exactly as it appears on the Eddi's screen, including any uppercase letters.
Your phone may say "Connected without internet". This is normal. Do not switch back to your home WiFi. Stay connected to the Eddi's network.
Step 4: Log in to the setup page
- Open a web browser. Google Chrome is strongly recommended, as Safari tends to block the setup address.
- Type 192.168.4.1 exactly into the address bar and press Go.
- You may first be prompted to set a device password. Requirements:
- At least 8 characters.
- One uppercase letter, one lowercase letter, and one number (e.g. Eddi1234).
- Do not use special characters such as
!,?, or$.
myenergi devices only work on 2.4 GHz WiFi, not 5 GHz. WiFi comes in two types, called bands, and most modern routers broadcast both at once. The 2.4 GHz band is slower, but it travels further and pushes through walls more easily, which is why most smart devices use it. Before you begin, make sure your router is broadcasting on 2.4 GHz. If your router uses the same name for both bands, it should work automatically. Otherwise, check your router settings first.
Step 5: Enter your home WiFi details
- The setup page will show a list of "Detected Networks." Select your home WiFi network.
- Enter your home WiFi password and tap Connect.
If the first attempt fails, try this quick fix before doing anything more involved: enable Airplane Mode on your phone, wait 30 seconds, then disable it and restart the process from Step 1. This clears any cached network state that may be interfering with the connection.
Expected result
Within a minute or two after entering your home WiFi details:
The Eddi's display will show a solid WiFi symbol, confirming it is connected to your home network.
The Eddi's temporary Access Point will automatically turn itself off once the home WiFi connection is established.
The light blue triangle on the Eddi tile in the myenergi app will disappear, and real-time data will begin to populate.
Once the process is complete, you can now turn your Mobile Data back on.
