Wireless Energy Manager – Quick Troubleshooting Guide
(Simpson & Partners Chargers)
What is the Wireless Energy Manager?
Your Wireless Energy Manager (WEM) is a small device installed near your fuse board.
It tells your Simpson & Partners charger how much electricity your home is using in real time. This allows the charger to:
- Use spare energy efficiently
- Prevent your home from being overloaded
- Automatically adjust charging speed based on demand
Think of it as the charger’s “energy traffic controller”.
Does It Need Charging?
Yes — occasionally.
The Wireless Energy Manager is designed to harvest power from your home’s electrical system. However, every 6–9 months it may need a manual top-up charge via USB.
This is completely normal.
What Happens If It Runs Out of Battery or Loses Connection?
If the Wireless Energy Manager:
- Runs out of battery, or
- Loses wireless connection
Your charger will automatically switch to a safe default charging speed.
This speed is set during installation and ensures your home cannot be overloaded.
Your charger will still work — it may just charge slower than usual.
How to Recharge the Wireless Energy Manager
Charging it is simple:
Step 1 – Locate the Device
It is usually installed near your fuse board (consumer unit).
Step 2 – Plug in a USB Cable
Connect a standard USB cable to the device and plug it into a USB power source.
Step 3 – Leave to Charge
Allow it to charge for up to 10 hours to fully top up.
Step 4 – Check It Has Power
Press the pair button on the back of the device.
If you see a blue light, the device has power.
That’s it — your system should now return to normal dynamic charging.
If It Still Isn’t Working
If:
- There is no blue light after charging
- The charger continues charging at a reduced speed
- You suspect it has lost connection
Please contact Simpson & Partners support and mention you have checked and charged the Wireless Energy Manager.
