Max! Eq3 windows sensor alternative

Hi all! I have a Max! Eq3 set of 2 radiator valves, 2 window sensors and max Cube Gateway.

It looks one of the window sensors died. I tried searching for original one to buy it, but couldn’t find it anywhere.
What are the alternative sensors which could be installed in existing configuration?

Please advise me.

Hey Bosko,

sadly there is no alternative as Max! can only be paired with Max!.
Max! is officially End Of Live, so you only can buy what’s left in stock or try to get something on the used market.
