## RCT adapter for ioBroker

Please note that this is a private project and that I (Andreas Ruttkamp) am not related to RCT in any way.
Read values of a RCT Power photovoltaics power converter.

## REMARKS

**IMPORTANT:
The RCT Inverter cannot distinguish between different clients asking for data.**
Opening the "RCT Power App" on a smartphone / tablet or running other adapters sending queries to the inverter (like EVCC), always leads to the adapter receiving unrequested data (visible in debug mode).
This data will be discarded and only requested data will be handled.

By using the "RCT Elements" field, one may select which data shall be read from the power converter.
If nothing is entered here, default will be used:

"battery.bat_status,battery.soc,battery.soc_target,battery.soc_target_high,battery.soc_target_low,dc_conv.dc_conv_struct[0].p_dc_lp,dc_conv.dc_conv_struct[1].p_dc_lp,fault[0].flt,fault[1].flt,fault[2].flt,fault[3].flt,g_sync.p_ac_grid_sum_lp,g_sync.p_ac_load_sum_lp,g_sync.p_ac_sum_lp,g_sync.p_acc_lp,g_sync.u_sg_avg[0],g_sync.u_sg_avg[1],io_board.s0_external_power,power_mng.is_heiphoss,power_mng.state,power_mng.u_acc_mix_lp,prim_sm.island_flag"

Other elements can be found in the code (file "rct/rc_core2.js"). Since this is not self descriptive, use at own risk!

The object "battery.bat_status" indicates the status of a connected battery:
* 0 -> charge/discharge (normal operation)
* 1 -> idle (no CAN-connection inverter -> battery)
* 3 -> connecting (inverter -> battery)
* 5 -> synchronizing (inverter -> battery)
* 8 -> calibrating - charging phase (0% --> 100%)
* 1024 -> calibrating - discharge phase (xx% --> 0%)
* 2048 -> balancing
	
The object "prim_sm.state" indicates the status of the inverter
*	0 -> 'Standby'
*	1 -> 'Initialization'
*	2 -> 'Standby'
*	3 -> 'Efficiency (debug state for development purposes)'
*	4 -> 'Insulation check'
*	5 -> 'Island check (decision where to go - grid connected or island)'
*	6 -> 'Power check (decision if enougth energy to start or not)'
*	7 -> 'Symmetry (DC-link alignment)'
*	8 -> 'Relays test'
*	9 -> 'Grid passive (inverter get power from grid without bridge clocking)'
*	10 -> 'Prepare battery passive'
*	11 -> 'Battery passive (off-grid)'
*	12 -> 'Hardware test'
*	13 -> 'Grid feeding'
