$ sudo dnf update
$ sudo dnf upgrade

$ sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
$ sudo dnf update
$ sudo dnf install mosquitto nohup

// Prepare serial port

$ udevadm info –attribute-walk path -n /dev/ttyUSB1 |grep -i serial

// Edit /etc/udev/rules.d/10-seplos.rules. this will ensure the same name of the serial port every time

SUBSYSTEM=="tty", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", ATTRS{serial}=="A9WT9VFQ", SYMLINK+="seplos", MODE="0660", GROUP="dialout"

$ sudo udevadm control --reload-rules && udevadm trigger

$ sudo ls -ld /dev/seplos
lrwxrwxrwx. 1 root root 7 Dec  6 09:27 /dev/seplos -> ttyUSB1

// Change the serial port permissions.
$ sudo usermod -a -G dialout $USER

// Get the script

$ git clone https://github.com/byte4geek/SEPLOS_MQTT.git
$ chmod 700 ~/SEPLOS_MQTT/query_seplos_ha.sh ~/SEPLOS_MQTT/run_bms_query.sh
$ touch ~/SEPLOS_MQTT/BMS_error.log

// Edit the script as per documentation, use /dev/seplos as serial port

// Test connection

$ ./query_seplos_ha.sh 4201

// Edit cron

$ crontab -e

@reboot nohup ~/SEPLOS_MQTT/run_bms_query.sh &
