Scheduling my bigger devices to run on solar

Questions & Help
1

Hey homeysđź‘‹

Im looking to start scheduling my larger devices so i can run them on the times that my solar panels generate the most energy. But im kinda stuck on where i can get the info from that i need.

I know what the energy consumption is per device but the problem is that i want to calculate when the best time is to start the device.
For example:
When: the time is 07:00
Then: Send notification: start the dishwasher at 12:00

And calculate this for every device.

But now for the question, where can i get the information for the amount of sun i get in the area and the time? the rest i could try to figure out but this is where i get stuck right now.

Hope you guys could help me out!

Hi Rik,
I don’t quite understand why you want to start these devices at a certain time. Why don’t you start the dishwasher when there is enough solar power available?

I’m using a mini switch beside the dishwasher to switch off the plug of the dischwascher, and using a flow like this…
WHEN power grid export is greater than 1800 watts
AND plug of dishwasher is off
THEN switch the plug on

Im working almost all the time when the sun is out and all our devices have a wait till start function, so in the morning before i leave i want to setup all the devices, so they can run when the most solar power is available

My washing machine, dryer and the dishwasher already have smart plugs so i know when they are running i only want to know when the best time is to start the devices

Ok, understood. But wouldn’t it be easier if the devices starts automatically when there is enough power?
Would your washing machine, dryer and dishwasher continue to run when you set a program, start the device and then switch off the plug?

If so, then you can switch on the plug of your device when the defined power consumption in your flow is reached. The device will then switch on when you export enough power.

If that doesn’t work, you can have a look at this app (I don’t use this app).

Ive never tried that to be honest, i always thought that they would reset themselves, but tomorrow ill try that.

For my dryer, washing machine and dishwasher it works that the program continues when the power is interrupted.
I use this for my flows by switching the plug on again when I have enough solar power.

Hi Rik.

Check out this link.

A bit further you will see a screenshot of my flow

Edit: I watched the screenshot that I posted myself but :sob:… je kan er geen soep van koken :rofl:

Thanks for the screenshot, and Yes i cant really see what going on but i get the idea!

The problem is that if i take away the power all my devices turn of and do go back to their old program. So the best thing that i can do is delayed start, but that means that i have to roughly know when the best time will be.

I think i need to calculate in a way when the amount of power is produced by adding: the wp of the solar panels, the amount of sun per our…

But that is where my brain stops working
