JSY-MK-194T Energy Counter¶

Description¶

The JSY-MK-194T Energy Counter measures the actual energy diverted to the load using the current readings from the JSY-MK-194T dual-channel power meter. Unlike the theoretical counter, this module uses real hardware measurements rather than calculations based on a declared load power, giving a more accurate account of the energy effectively consumed.

This package shares the UART communication layer with the JSY-MK-194T power meter via the jsy-mk-194t_common.yaml package. Both packages must be included together in your configuration.

Common Configuration¶

Shared configuration

solar_router/jsy-mk-194t_common.yaml configures UART communication and is used by both the power meter and the energy counter.

This file manages communication with the board. If you wish, you can expose JSY-MK-194T measurements in Home Assistant; see the example below.

packages:
  solar_router:
    url: https://github.com/hacf-fr/Solar-Router-for-ESPHome/
    refresh: 1s
    files: 
      # JSY-MK-194T management
      - path: solar_router/jsy-mk-194t_common.yaml
        vars:          
          uart_tx_pin: GPIO26
          uart_rx_pin: GPIO27
          uart_baud_rate: 4800
          AP_Ch2_internal: "false" # optional, allows displaying one of the JSY-MK-194T sensors

JSY-MK-194T Sensor Options¶

Voltage on Channel 2 is not implemented; the meter uses the Channel 1 voltage.

Energy Counter Configuration¶

To enable the energy counter, simply add it to your configuration as shown in the example below:

packages:
  solar_router:
    url: https://github.com/hacf-fr/Solar-Router-for-ESPHome/
    refresh: 1s
    files: 
      - path: solar_router/energy_counter_jsy-mk-194t.yaml

For a complete implementation example, refer to the JSY-MK-194T example.

Variables¶

Variable	Required	Default	Description
—	—	—	This module has no configuration variables. It uses the JSY-MK-194T measurements configured via `jsy-mk-194t_common.yaml`.
