(under construction)


This 'Energy!' node enables monitoring of AC mains power or DC power up to 15A. Additionally, this node incorporates a mains relay so that downstream devices can be shutdown or given a low-level reset.

Use this device to monitor devices and machinery to detect increased power consumption due to wear and tear. Or integrate the devices with a payment portal for metered power connections with cut-off capability upon excess current or kWh budget exceeded.
