Subject Re: Tools to retrofit machines with StreamPipes
Date Mon, 13 Jan 2020 21:47:01 GMT

just in case some of you are interested in gathering power information of machines and add
human generated label to the data.

I found a cool app called MQTT Dash, which we use instead of hardware buttons for user input
next to machines. 
Originally it was designed as a dashboard app for your smart home and is very simple to use.
To gather user input (e.g. scrap parts on a machine) create a dashboard with buttons operators
can press. For each interaction an event is triggered which is read by a StreamPipes Connect
Those events are stored in a database and can later be used as labels to train machine learning

For the power sensors, I found those [1]. It seems that they can generate high frequency events
of the current power consumption of the connected machine. There is also a MQTT version available.
