These are the ones i have...

Welcome to the Forum ??

This is V1

V2 would be written on the package, and has a small hole on the front to be able to press the inside button with a thin wire without having to open the sensor.

Ok, thanks!

Btw, i need to get some info about hos these sensors are supposed to work:)

How often are they expected to wake up from sleep?

On which side should i have the magnet??

Is it supposed to wake up immediately when its opened/closed? Because mine does not. It seems to change state "sometime later... perhaps".

The magnet must be on the side where the reed contact is located. There is also a small arrow on the housing of the sensor.

It will wake up within 2 to 3 seconds after opening the window.

It is important to assign fixed Ip outside the DHCP range. Saves battery and the transmission is much faster than if only DHCP is used.

How to improve work of battery operated Shelly devices

If the door remains closed, changes in the light intensity can cause the DW1 to wake up.
These are adjustable in the ice positions.

Without any change the sensor remains in deep sleep mode.

Hi,

How do I know what version (1 or 2) I have?

I have a mix of these devices installed, and they are not seeing update (though there is one).

Otherwise put, what happens when I upload the firmware of 2 to a device of 1st gen?

Or how can I by software determine the generation 1 from generation 2?

Thanks!
