Description

The Gelidus Research Expandable 2 or 3 Phase Power Meter (PM1v2) monitors energy usage of your AC mains panel and optional circuits in real time.

This kit includes 1 x AC Cord, 1 x Main Board with External Antenna, 3D Printed Enclosure, 2 or 3 Current Transformers as selected options and an AC Wire Clamp.

The unit is delivered pre-assembled and voltage/current calibrated with the CT options ordered.

A total of 3 channels are provided in the base kit, you can optionally add a 3 channel riser which fits in the same base kit enclosure.

The base board 3D case supports a single additional riser as printed, for additional risers you can add-on snap lock stackable plastics hosting up to 5 riser boards

This 3 Phase Power Meter provisions:

Energy usage data collection with ESPHome and Home Assistant
- View the energy usage of your entire home.
- Monitor costs of your electric appliances.
- Review and graph historical energy data.
- Monitor your Day, Hour, Week, Month, Year total Kilowatts (KWH)
- Deep insight with Active, Apparent, Harmonic Power, Phase Angle, Peek Current and Power Factor data.
- Optional Voltage Reference Transformers (VRT)
- 3 channel expansion modules
Reliable non-intrusively connected energy monitoring hardware!
- Cost effective, very accurate and pre-calibrated.
- Powerful 160Mhz dual core ESP32-C6 wireless module coupled with an ATM90E32.
- Antenna included for exceptional WiFi/Thread range.
- IEEE 802.15.4 Thread, Matter, Zigbee and Wifi 6 capable hardware.
- Works with ESPHome Wifi, BLE or Thread components.
- Powered via an AC mains isolation transformer.
- Metering is connected via non-intrusive current transformer phase line clamps.
- Completely isolated mains power supply and mains monitoring circuit connections
Flexible power monitoring capacity options based on CT selection
- SCT-013 13mm Split Current Transformer – 100A per phase (100A service )
- SCT-016 16mm Split Current Transformer – 120A per phase (100A service ) 0.5%
- SCT-023 23mm Split Current Transformer – 200A per phase (200A service ) 0.5%
- SCT-024 24mm Split Current Transformer – 200A per phase (200A service )

Always measure the service line diameter to ensure you chose the right CT fit.

Software Elements:

The Gelidus Research Expandable 2 or 3 Phase Power Meter board is designed to run on ESPHome frameworks. ESPHome integration with Home Assistant (HA) is ideal for providing a rich user interface. Adding the PM2 to ESPHome and HA is easy using the preinstalled PM2 captive portal or directly with the USB-C programming port. Once connected to your WIFI network you can interface to HA using one of the provided install guides. ESPHome network connectivity is via Thread or the standard WiFi 6 mode.
