Create flow when a device's current is between 2 values for a certain period of time

[Martijn_Swart]

Hi there,

I would like to crate a flow based on the following parameters:

• power current used by a device is between 1.8A and 2.2A
• in a time period of about 10 minutes

anyone has an idea on how to achieve this?

If you own a Homey Pro, this is a way to achieve it, Martijn. And welcome here!

This is also possible when using standard flows, you’ll need 2 flows:
1 for the power change trigger
1 for the timer finished trigger

Oh, and this is how to find the right tag of a device

Thanks very much! I’ll give it a try.

Some questions:

• What happens if power is fluctuating between 1,8 and 2.2?
• What happens if power is between 1,8 and 2.2 for a minute within 10 minutes?

And are the answers what you want/need??

[Martijn_Swart]

Don’t know yet. It’ll need a bit of testing and tweaking.

What happens if power is fluctuating between 1,8 and 2.2?

Good point. I think an additional “amps within range” YesNo variable needs to be set, which then drives the timer. This eliminates the fluctuation triggers.

Nothing I hope

If you need a translation, please let me know.

You are using Pause where I think you could better use Stop (As DirkG)

Doesn’t matter if Pause or Stop is used when we start the timer with the “Start or Replace” card.
It’s a different story when one uses “Start or Resume” card. But we don’t in this case.

I still don´t understand the where this is related with the above

@Hielke_de_Jong

[Peter_Kawa]

This works for me, the variable now controls the timer as in-between

[Hielke_de_Jong]

My mistake because of the use of the Pause and not seen the use of the start or replace, I was thinking after the pause the time would continue. So that the timer could reach 10 minutes separated over time.

But indeed you use the start or replace so nothing unexpected will happen.

[Martijn_Swart]

Took some time to do proper testing and tweaking, but it works great!

Thanks for all the advice.

This is all great info. The issue I have is the Ikea Inspelning and when used in the “and” card mode it only gives ONE option:

Which seems like particularly weak sauce to me. If I could link two “When” cards together as both needed conditionals that might work, but either way, those would likely need to come after a “When” card for when power changes.

I guess I need to go find other on/off switches (for the US) that have a few more… options.

[DirkG]

Maybe you can share what you want to achieve?

@KenZ

and when used in the “and” card mode it only gives ONE option:

For most “And” options, you’ll need to use one of the logics cards. A main reason for developers not to create additional ‘And’ cards for standard conditions.

Apps often provide for info through so called ‘tags’. Tags can be considered as variables controlled by apps only. You can use those tags to read out their values.
