=== One-phase sensor PM1-E-D ===

  *   Wire it to communication bus,
  *   press and hold the push-button on the power sensor until it appears **-SEt-** on display,
  *   it should appear in configurator as new device, click on button **add** next to the source or consumer where sensor should be assigned,
  *   repeat procedure for next PM1-E-D.

=== Three-phase sensor PM3-E-D ===

It is possible to set address manually according to table above before adding it to communication bus or 
  * **Connect** communication bus (to only one power-sensor)
  * In HEMS Configurator power-sensor should appear as a "new device"
  * Click on the **" add"** button next to the source or consumer that the sensor is measuring
  * Connect communication bus to the next power-sensor and repeat procedure

**Note**: .Allowed addresses are 150,154,161-167.

=== Without grid power sensor ===

  *   **Virtual grid PS** is an option if no grid meter is used. Power, current and energy will be calculated from other power sensors.

==== Power-sensor removing ====

=== One-phase sensors PM1-E-D ===

  * Make sure the "new device" is empty
  * Press the button on power-sensor until **-Set-** appears on the display
  * In HEMS Configurator press **"del"** button next to the sensor
  * After a few seconds, the sensor should appear as the "new device"
  * If desired, the sensor can be removed or it can be assigned to another device

=== Three-phase power-sensor ===

  * Make sure the "new device" is empty
  * In HEMS Configurator press **"del"** button next to the sensor
  * After a few seconds, the sensor should appear as the "new device"
  * If desired, the sensor can be removed or it can be assigned to another device
