Estimate number of variables

«Back to editions

A certain number of variables is required to use a device/instance. For example, a humidity sensor uses 2 variables (1 for temperature, 1 for humidity).

The number of variables depends on the used system. However, usually one variable is required for every physical input/output in IP-Symcon. The following tables allow a coarse estimation.
