/*********************************************************************************************\
* Sonoff Stackable Power Manager
*
* {"NAME":"Sonoff SPM","GPIO":[0,0,0,0,3200,5536,0,0,672,704,736,0,3232,0,5600,0,0,0,0,5568,0,0,0,0,0,0,0,0,544,0,0,32,0,0,0,0],"FLAG":0,"BASE":1}
*
* Things to know:
* Bulk of the action is handled by ARM processors present in every unit communicating over modbus RS-485.
* Each SPM-4Relay has 4 bistable relays with their own CSE7761 energy monitoring device handled by an ARM processor.
* Green led is controlled by ARM processor indicating SD-Card access.
* ESP32 is used as interface between eWelink and ARM processor in SPM-Main unit communicating over proprietary serial protocol.
* Power on sequence for two SPM-4Relay modules is 00-00-15-10-(0F)-(13)-(13)-(19)-0C-09-04-09-04-0B-0B
* Up to 180 days of daily energy are stored on the SD-Card. Previous data is lost.
* Tasmota support is based on Sonoff SPM v1.0.0 ARM firmware.
* Energy history cannot be guaranteed using either SD-Card or internal flash. As a solution Tasmota stores the total energy and yesterday energy just after midnight.
*
* Tasmota features:
* - Up to 7 SPM-4Relay units supporting a total of 28 relays.
* - Button on SPM-Main initiates re-scan of SPM-4Relay units.
* - SPI master to ARM (ARM firmware upload from ESP using EasyFlash not supported).
* - Ethernet support.
* - Gui rotating energy display for 4 relays at a time.
* - Gui optimized for energy display.
* - Blue led equals Tasmota WiFi status.
* - Yellow led lights if no ARM connection can be made.
* - Yellow led blinks 2 seconds if an ARM-ESP comms CRC error is detected.
* - Persistence for module mapping, total energy and energy yesterday
* - Supported commands:
* SspmDisplay 0|1 - Select alternative GUI rotating display either all (0) or powered on only (1)
* SspmDump 0|1 - Select shortenend (0) or full (1) serial receive buffer dumps
* SspmEnergyTotal<relay> - (p)reset total energy without today's energy
* SspmEnergyYesterday<relay> - (p)reset energy yesterday
* SspmHistory<relay> - Retrieve daily energy of last six month (as defined by ARM firmware)
* SspmIAmHere<relay> - Blink ERROR in SPM-4Relay where relay resides
* SspmLog<relay> [x] - Retrieve relay power state change and cause logging
* SspmMap 0 - Start a scan to fill default mapping
* SspmMap 2,3,1,.. - Map scanned module number to physical module number using positional numbering
* SspmOverload<relay> 0 - Set default overload detection parameters as read from module during initial scan
* SspmOverload<relay> <delay>,<min_power>,<max_power>,<min_voltage>,<max_voltage,<max_current>
* SspmOverload<relay> 0,0.10,4400.00,0.10,240.00,20.00 - Set default values using comma separated options
* SspmOverload<relay> 0 0.10 4400.00 0.10 240.00 20.00 - Set default values using space separated options
* SspmOverload<relay> 10,12.3 - Enable overload detection after 10 seconds for MinPower
* SspmOverload<relay> 10,0,22.2 - Enable overload detection after 10 seconds for MaxPower
* SspmOverload<relay> 10,0,0,0,235.2 - Enable overload detection after 10 seconds for MaxVoltage
* SspmScan - Rescan ARM modbus taking around 20 seconds
* SspmReset 1 - Reset ARM and restart ESP
*
* Todo:
* Gui for Overload Protection entry (is handled by ARM processor).
* Gui for Scheduling entry (is handled by ARM processor).
*
* Nice to have:
* Support for all 32 SPM-4Relay units equals 128 relays (restricted due to internal Tasmota register use)
*
* GPIO's used:
* GPIO00 - Bootmode / serial flash
* GPIO01 - Serial console TX (921600bps8N1 originally)
* GPIO03 - Serial console RX
* GPIO04 - ARM processor TX (115200bps8N1)
* GPIO05 - ETH POWER
* GPIO12 - SPI MISO to MOSI ARM output (pin36 - PB15)
* GPIO13 - SPI MOSI to MISO ARM input (pin35 - PB14)
* GPIO14 - SPI SCLK to ARM input (ARM pin34 - PB13)
* GPIO15 - ARM reset (output) - 18ms low active 125ms after restart esp32
* GPIO16 - ARM processor RX
* GPIO17 - EMAC_CLK_OUT_180
* GPIO18 - ETH MDIO
* GPIO19 - EMAC_TXD0(RMII)
* GPIO21 - EMAC_TX_EN(RMII)
* GPIO22 - EMAC_TXD1(RMII)
* GPIO23 - ETH MDC
* GPIO25 - EMAC_RXD0(RMII)
* GPIO26 - EMAC_RXD1(RMII)
* GPIO27 - EMAC_RX_CRS_DV
* GPIO32 - Blue status led2
* GPIO33 - Yellow error led3
* GPIO35 - Button
* #define ETH_TYPE ETH_PHY_LAN8720
* #define ETH_CLKMODE ETH_CLOCK_GPIO17_OUT
* #define ETH_ADDRESS 0
*
* Variables used:
* module = 0 to 31 SPM-4Relays
* channel = 0 to 3 or 01, 02, 04, 08 Bitmask of four relays in module
* relay = 0 to 127 Relays
