PAUSE_END phase trigger BATTERY_VALUE, BATTERY_OVERVOLTAGE and SOC_PLAUSABILITY_ERROR

[luipir]

Expected Behavior

Normal work of the emulator wthout triggering any alarm or error

Actual Behavior

when PAUSE_END is reached, a set of error ar triggered as in the image

The error is triggered every day as 18:06

Steps to Reproduce the Problem

Settings

detailed configuration:

in resume the conf is:

#define NISSAN_LEAF_BATTERY

/* Select inverter communication protocol. See Wiki for which to use with your inverter: https://github.com/dalathegreat/BYD-#define BYD_CAN  //Enable this line to emulate a "BYD Battery-Box Premium HVS" over CAN Bus

/* Select hardware used for Battery-Emulator */
#define HW_STARK

/* Contactor settings. If you have a battery that does not activate contactors via CAN, configure this section */
#define PRECHARGE_TIME_MS 500  //Precharge time in milliseconds. Modify to suit your inverter (See wiki for more info)
#define CONTACTOR_CONTROL  //Enable this line to have the emulator handle automatic precharge/contactor+/contactor- closing sequence (See wiki for pins)
#define PWM_CONTACTOR_CONTROL  //Enable this line to use PWM for CONTACTOR_CONTROL, which lowers power consumption and heat generation. CONTACTOR_CONTROL must be enabled.
#define PERIODIC_BMS_RESET  //Enable to have the emulator powercycle the connected battery every 24hours via GPIO. Useful for some batteries like Nissan LEAF

#define CRYSTAL_FREQUENCY_MHZ 8  //CAN_ADDON option, what is your MCP2515 add-on boards crystal frequency?

#define WIFICONFIG  //Enable this line to set a static IP address / gateway /subnet mask for the device. see USER_SETTINGS.cpp for the settings
#define WEBSERVER  //Enable this line to enable WiFi, and to run the webserver. See USER_SETTINGS.cpp for the Wifi settings.
#define WIFIAP  //When enabled, the emulator will broadcast its own access point Wifi. Can be used at the same time as a normal Wifi connection to a router.
#define MDNSRESPONDER  //Enable this line to enable MDNS, allows battery monitor te be found by .local address. Requires WEBSERVER to be enabled.

Quick triage, The bug is most likely related to PERIODIC_BMS_RESET that is pausing the emulator every day.

[dalathegreat]

Should be solved with 8.2.0!

[luipir]

I'll give a feedback when new pause will be triggered automatically. Doing it manually do not trigger new error events (other that inverter that alert me because of lack of voltage reading). So IMHO it could be considered solved

[dalathegreat]

Super! BTW I have one more PR related to making the periodic pause better: #814

[luipir]

FYI after moved to 8.2 the pause still trigger something (CAN_OVERRUN)

the inverter still alert me that a pause happen and lost BMS communication. speculating a possible configurable solution is to clone previous messages to avoid to alert some inverters during bms pause

[dalathegreat]

Both those issues are what PR #814 is aiming to fix!
