This fork from wills106 Added single-phase meter and device auto-discovery.

homsassistant-IamMeter-modbus

IamMeter Modbus custom_component for Home Assistant Support Modbus TCP

Firmware version >= 75.82

You can have multiple instances of this Integration, just change the default Prefix from IamMeter to something else. Ie IamMeter Main or IamMeter Garage

Supports:

• WEM3080
• WEM3080T

IAMMETER

---

IAMMETER provides both a bi-directional single-phase energy meter(WEM3080) and a bi-directional three-phase energy monitor (WEM3080T). Both of them can be integrated into Home Assistant.

Installation

---

Manual Installation

1. Copy iammeter_modbus folder into your custom_components folder in your hass configuration directory.
2. Restart Home Assistant.

Installation with HACS (Home Assistant Community Store)

1. Ensure that HACS is installed.
2. In HACS / Integrations /explore&download repositories/iammeter, add the url the this repository.
3. Search for and install the iammeter integration.
4. Restart Home Assistant.

Configuration

It is configurable through config flow, meaning it will popup a dialog after adding the integration.

1. Head to Settings --> Devices & Services--> ADD INTEGRATION
2. Add new and search for iammeter_modbus
3. Enter a name for your meter. It suggests "IamMeter" by default, but if you plan to read multiple make it a unique name.
4. Enter a IP to the IamMeter module. For example: "192.168.2.15" .
5. SUBMIT --> FINISH.
