How to reconnect your myenergi hub
Why has my myenergi app stopped updating?
If your myenergi app shows your Eddi or Zappi as offline, but your solar system is still producing power, the problem is usually the myenergi hub's connection to your home network, not your solar system. This page explains how to tell the difference and how to reconnect your hub after a router or password change.
Your inverter will usually still show as online in its own app, and that is expected. The inverter and your myenergi devices use completely separate monitoring platforms, and only one of them has dropped offline.
Two separate monitoring systems
If your system has both an inverter and a myenergi device, you have two separate monitoring apps, and they do not talk to each other:
Your inverter app will be one of these, depending on the brand: SolisCloud, EcoFlow, iSolarCloud (Sungrow), FusionSolar (Huawei), mySigen (Sigenergy) or SofarCloud (Sofar). Those are the names to search for in your phone's app store.
If you are looking for FusionSolar on an Android phone, note that Google Play often carries an out-of-date version. Download it directly from Huawei's own support site, or scan the QR code on the side of your inverter instead. iPhone users can use the normal Apple App Store.
| App | What it monitors |
|---|---|
| Your inverter app | Inverter, solar generation, battery |
| myenergi app | Eddi (immersion diverter), Zappi (EV charger) |
If your system looks “offline”, check your inverter app first. If your inverter app confirms your inverter is generating and operating normally, your solar system is working fine. It is your myenergi hub connection that has dropped. This is the most common cause of a confusing “my system is offline” report.
Is it the hub or the inverter?
These signs together tell you it is the myenergi hub that has dropped, not your solar system:
The Eddi or Zappi tiles in the myenergi app appear disconnected, or show a warning triangle, and data is no longer updating.
Opening your inverter app confirms the inverter is online and producing power. If the inverter is working, the problem is not the solar system.
Your lights, sockets, and broadband are all working. It is only the myenergi devices that have dropped off the network.
Common causes
The myenergi hub connects your Eddi and Zappi to your home network, and through it to the myenergi cloud. The connection is usually lost for one of these reasons:
A new router means a new network name and password, so the hub can no longer find the network it was connected to.
If your WiFi password was changed, or the router was reset to factory settings, the hub is left with old network details that no longer work.
A power cut can leave the hub, router, and devices starting up in the wrong order, so the connection does not come back automatically.
How to reconnect your myenergi devices
Work through these steps in order. In most cases, a clean restart of your hardware will force the system to find your router and log back in automatically.
How to find your myenergi hub
The hub is the part that connects your Zappi and Eddi to your home network, and through it to the myenergi app. It is one of two things, and you only need to find out which one you have:
- A separate hub box. A small white myenergi box with glowing green lights, sitting near your broadband router. Older myenergi systems came with a separate hub box like this.
- No separate box at all. Most systems installed in recent years do not have one. Instead, the hub is built into your main myenergi device, such as your Zappi charger or your Eddi hot water diverter, as a "virtual hub" (vHub). If you cannot find a small white box near your router, you almost certainly have this setup.
You do not need to change any settings to work this out, and you will not be opening anything up. Whichever setup you have, the fix is the same: restart the device that holds the hub. Use the step below that matches what you found.
- Reboot your home router first: switch your home broadband router off at the wall, wait 30 seconds, and turn it back on. Let it fully restart, which takes about 3 to 4 minutes. Often, a router refresh is all it takes.
- If you have a physical Hub box: look near your broadband router for a small white myenergi box with glowing green lights. Unplug the power cable from the back of it, wait 10 seconds, and plug it back in. Wait for the lights to settle.
- If you do not have a physical Hub box (vHub systems): modern myenergi setups do not need a separate box. Your main device, such as your Zappi charger or Eddi hot water diverter, has a built-in "Virtual Hub" (vHub) inside its internal computer.
To refresh this virtual hub, you must restart the main device itself. Locate the isolation switch or breaker switch for your Zappi or Eddi, turn it OFF, wait 10 seconds, and turn it back ON. This forces the internal computer chip to clear its stored settings and re-establish a link with your home router.
- Check the myenergi app: give the entire system about 2 minutes to settle down, then open your myenergi phone app to confirm your devices are showing live data and are securely back online.
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. If your devices will not reconnect after a restart, check that your router is broadcasting a 2.4 GHz network and that your devices are within range of it. Not sure how to check? Here is how to check your WiFi is 2.4 GHz.
If the Eddi itself will not reconnect to WiFi, rather than just the hub, follow our step-by-step Eddi WiFi reconnection guide, which walks you through connecting your phone directly to the Eddi to send it your home WiFi details.
Expected result
After reconnecting, you should see the following within a minute or two:
The Eddi and Zappi tiles no longer show a warning triangle or “offline” status.
Real-time generation, hot water, and charging data begins to populate in the app as normal.
No re-registration is needed. Once the hub is connected correctly, your devices will appear automatically.
