Mapping the official app to OIDs

By default, the official app does not display which OIDs the values it displays correspond to and it is not always straight forward to find the correct OID in the Registry. This page provides a mapping for some of the values.

Screenshots where taken from the official Android App (see RCT Power App on the vendors homepage) version 2.500 from 12 Nov 2020, things may look different in newer versions or in the iOS app. The images have been slightly altered to add annotations for easier referencing.

The setup shown here uses a single RCT Power Storage DC 6.0 with RCT Battery Storage battery and RCT Power Switch which is equipped with an RCT Power Sensor.

Note

There is no guarantee that the information is correct, and it may change anytime without notice.

Main overview

The main overview screen is the first thing the app displays after startup. It's showing a diagram that displays the connected components (solar panels, the inverter, battery, power switch) as well as household power consumption and the grid load. Coloured, dashed lines visualize both what is connected to which device and how much energy is flowing (by speeding up or slowing down the animation as well as changing the colour to visualize generation and consumption).

Tapping one of the icons opens tabular views that go into detail about the selected element, more on that later. The image has been edited to add markers, click to zoom:

RCT Power App (Android) main view, displaying connected components such as solar panels, the inverter, battery as well as some measurements about energy generation / consumption and battery state of charge. Annotations were added to refer to individual components.

Marker	OID	Description
	`android_description`	Device name
	`g_sync.u_sg_avg[0]`	Solar generator A voltage (see Solar generator)
	`dc_conv.dc_conv_struct[0].p_dc_lp`	Solar Generator A power
	`prim_sm.state`	Inverter status (enum) (see Inverter)

	`power_mng.u_acc_mix_lp`	Battery voltage (see Battery)
	`battery.soc`	Battery State of Charge
	`battery.soc_target`	Target State of Charge
	`g_sync.p_acc_lp`	Battery Power (negative for discharge)
	`g_sync.p_ac_load_sum_lp`	Load household - external Power (see Household power)
	`g_sync.p_ac_grid_sum_lp`	Total grid power (see Power grid)
		Power Switch / Power Sensor (see Power switch / Power sensor)

Values fuer the second solar generator ("Input B") can be retrieved by changing the number in square brakets from 0 to 1:

Voltage A: g_sync.u_sg_avg[0]
Voltage B: g_sync.u_sg_avg[1]

Note

The app will cycle between the status and the active events in the (D) position if there are active events, such as over- or undervoltage conditions.

Solar generator

The inverter used here has two inputs for solar generators, which are usually strings of multiple solar cells.

As before, [0] denotes generator A and [1] denotes generator B. Values without a number don't distinguish between solar generators. The "Description" is the text in the left column of the table as displayed by the app.
