Long story short: almost everything electronic in the industrial space uses <a href="https://modbus.org/" target="_blank" rel="noopener noreffer ">Modbus</a> to communicate, typically with a <a href="https://en.wikipedia.org/wiki/Programmable_logic_controller" target="_blank" rel="noopener noreffer ">PLC</a>. While Home Assistant <a href="https://www.home-assistant.io/integrations/modbus/" target="_blank" rel="noopener noreffer ">does have support</a> for the Modbus protocol, but wanted to use a PLC that could manage the sensors directly and expose the values over the network in a more standard format; MQTT.</p>
