Channel 65 adjusted for the kwh.I am able to read values.But i need some calculations on it. Let’s say; 14.08.2018 at 08:00 Chnanell 65 is 1000 kwh 14.08.2018 at 16:00 Channel 65 is 2000 kwh i want to calculate this difference. Thank you very much August 14, 2018 at 2:03 pm #4135 MikhailModerator Hello, This calculation is difficult to implement using built in formulas because they work with current values. I suggest Elastic Report plugin, please check the demo which performs what you need. August 14, 2018 at 2:06 pm #4136 MikhailModerator The example shows daily difference. Elastic Report also supports hourly difference. In case of 8 hours difference, we can discuss implementing this feature.

How can I do this? Also, is it possible to implement a digital momentary start/stop? Thanks January 4, 2019 at 1:17 pm #4813 MikhailModerator How can I do this? For example, Cnl * 10 is it possible to implement a digital momentary start/stop? Please clarify the question.
