Sadly because of that my boss sold it as platform for non dev tech people to monitor production hardware (like weaving machines) using nodered and modbus, it's a shitty idea to do it in node red, it kinda works tho, but it's error prone, slow(to respond) and just writing some simple specific software for it would have solved the use case of the customer in a way better way, but it's great for conferences/workshops/presentations to just link up a node to a SMS /IM Provider to have some kind of wow effect
