Is there a way of writing an average device value to another device?

[Join]

Hi!

I got a device that read realtime power consumption in my home.

I am looking for a way to calculate the last hour power (kW) consumption and write the result to a virtual device every 10seconds or so.

Resulting in valus like: 2.5kWh, 1.03kWh, 0.85kWh etc.

Is there a way to do this?


Best regards

Create a virtual device for average power (kW)
When your original device is "set" (every 10 sec)
just have ET update your virtual device with ((new value+virtual device value) /2)


You could create a third VD to calculate/write the hourly energy consumption (kWh) if needed.


Check ET help for "set device to expression"

Here is an example.

This is a graph collected with the Device History plugin:

It shows the current Last hour power consumption, and the result is 2,7kWh.

I am looking to see if it's possible to do with EasyTrigger.

Mabye with 60 virtual devices, adding together /60=average-ish?

You're trying to reinvent the wheel. Simply pull the Average value for the last hour from Device history and put that value in a virtual device that you can use in Events, HSTouch, etc.

I don't use Device History (I use Jon00's Charting) but I'm sure there's a way to pull the Average value calculated in the chart you're showing.
