Good morning, I just installed a Homey at home, so I’m finding out. I am looking to measure the consumption of a machine with a Fibaro Wall Plug Z-wave socket I would like when it is turned on to increment a variable to measure its consumption, I cannot find my way to do it. So at any time I can know its total consumption Do you have a lead? Thanks in advance ---

Hello, Thank you for this answer and the indication of the app. This is indeed a good solution! On the other hand, we have a bi-hourly meter with different night and day rates. I don’t have the impression that the app can make a distinction? ---

Yes you can set different rates by flows. I’ve also a meter with high and normal rates, and I saved the actual prices in variables, which are used in the tariff entry of the flowcard ![Screenshot_20230912-224547_Homey](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/8/3/83c1c697758bafe998795aa24b9321a16464765d.jpeg) ---

Hello, Thanks for the reply. I don’t see how to set up different rates and schedules. In the virtual device settings, there is no such possibility. Can you give me an example ? Thank you
