Python bringt für so eine einfache Aufgabe sehr viel Overhead mit. Ein Bash Skript wäre hier besser.
Vorschlag:

#!/bin/bash

# This script is used to trigger an update of a secondary openWB
# It is intended to be run on the primary openWB
# The primary openWB will send a mqtt message to the secondary openWB
# The secondary openWB will then update itself
#
# parameters:
# 1: the ip address of the secondary openWB

# check if the ip address is given
if [ -z "$1" ]; then
  echo "Please provide the ip address of the secondary openWB"
  exit 1
fi

# get the ip address
ip=$1

# check if ip address is valid
if ! [[ $ip =~ ^((25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)$ ]]; then
	echo "The ip address is not valid"
	exit 1
fi

# check if mosquitto is installed
if ! command -v mosquitto_pub &> /dev/null; then
  echo "mosquitto is not installed"
  exit 1
fi

# send the mqtt message
mosquitto_pub -h "$ip" -t "openWB/set/command/primary/todo" -r -m '{"command": "systemUpdate", "data": {}}'

# done
exit 0

Der Befehl mosquittp_pub ist ausreichend.
