Limit power with Shelly

frederenke

Hello,

I'm fairly new to the Shelly system and want to solve something I could not find on the web.

I have one goal:

- I want to switch a power outlet based on the state of one or two windows.

- If both windows are closed, the outlet should only allow a specific load (~10W).

- If one of the windows is open the power outlet should be on without a limit.

I have two questions:

- Is it possible to connect two window switches to one Shelly?

- Is it possible to limit the power outlet based on the state of a window switch?

Thanks!

PS I assumed the Shelly1 would be the device to go. However, if something else is appropriate, feel free to shift this thread

First yes it is possible to connect two other devices to one.

Second (need to be tested)

You need a Shelly1PM because the Shelly1 can't measure.

For your wish:

You can change the max power per url, but you need to turn on the device by your self.

Changing the max power when closed to 10W with this

Code

http://ip/settings?max_power=10

and when open (you need to fill up all open actions)

Code

http://ip/settings?max_power=3500

Thanks for your quick reply! Can Shelly Plug also do the job? As far as I read it also has a power meter.

I am not sure if Shelly1PM would fit behind the plug....

SebMai

the Shelly1PM has the same size like the Shelly1.

It should work with an plug too, but I can't look or test, because I haven't one.

Eventually can another member look if the url is working there too

seems to work. I have this from the help
