This might be why…..

When you received your HE203 system, you would have received another small meter with it.  This is NOT A FREE gift !

In order for the HE203 to work, you MUST connect the small meter (The Tiny) to the HE203.  The HE203 controls the money and The Tiny, tells the HE203 how much electricity has been used.  Without the Tiny the HE203 does not know if any electricity is being used.

So please make sure that The Tiny is connected to the HE203 – without it your tenants will be receiving FREE electricity/water/gas.
