interesting. I have looked on many app systems but not found any good yet. From my side i would like to have read/write from/to mqtt or kafka included in the app so i could have live dashboard and feedback buttons to use for example start/stop of order or report back machine faults. i have not found any good app builder that is easy to use yet.. With ease of use i mean that a shop floor manager or similar could create a new dashboard him/her self.
