Graph for power [W]?

[DanDanDanK]

Hello,

I installed the PM mini Gen3 to measure my ventilating system. I was interested to see when the system uses how much power.

However, I see the power integrated over time, i.e., the energy consumption in [Wh]:

Further, I see a graph of the voltage over time. This is boring. I don't expect much to happen there and I think this is a real waste of UI real estate.

I'd prefer to see a power graph there.

Can I configure this and how? Thank you.

I think at the moment we have to live with it. Also for me, live values and diagrams of following values would be the choice:

- instantaneous current 

- instantaneous power

- energy integrated (summed up) over time

- voltage no diagram needed, but if instantaneous value could be seen somewhere would be ok

When I install a new Shelly then I try to make some documentation. Very popular is a power graph with a temperature graph. 
I'm using "Shelly Scanner" for that. The image shows a graph of a Shelly 1PM controlling a 1800 Watt boiler.

Thanks! Very cool tip, software is absolutely useful

Thanks! Still I'm disappointed that there's not power graph and that I have to resort to other means to generate one.

I have no idea why Shelly managers made the decision to include a completely useless voltage graph but left out the power graph. 🙄

Just my 10 Cents: Drawing a graph with energy (kW/h) over a time scale (h) cancels the time component. Thus, energy per time is power…

Waste of energy if I do this. Clearly, this should be included in the firmware so it is available for every user and only Shelly has the power to do this. 😁

The energy graph does this for you. Tried to give you a hint to interpret the energy graph deeply…

You are right. As long as the graph has a resolution of 1 h, the energy value in [Wh] is the same value for power [W]. However, I had hoped for a graph with higher resolution (minutes or even seconds) where this simple relation does not hold true any more. Sadly, that high a resolution is (currently) not provided in the Shelly app/cloud. I guess I have to download Shelly Scanner for this.

The problem is that it shows half hour averages not the instantaneous power. So, for example if you want to see whether a heatpump is cycling you can’t do that unless you collect the W data (vs Wh). Both graphs are useful 🙃

maybe 80% of Shelly users are ok with the existing graphs...if you need more details just pay for Premium Account. It is up to you not to Shelly!
