Hello everyone! I intend to buy a window opening sensor, and my question is if it’s possible to assign it a specific sound (let’s say a siren) to notify me when it’s opened. I already have several devices connected, so it would be great if this particular one could notify me in this way. Thank you, and have a great week! ---

There are Zigbee sirens on the market. But they shouldn’t be useful as a deterrent. Rather as a doorbell. What I have is a classic12V-24V siren and the Sonoff SV module 5-24 V. The classic siren is a “real” one and the Sonoff module makes it smart. ---

I apologize if my questions seem silly; I am very ignorant on the subject. I will go with the idea you suggested as it seems to be the best one. Now, my question is: suppose I install a sensor on a door, and when it opens, it triggers the alarm, which will obviously work as a security system (that’s what I intend). The issue I’m facing is that it would be “armed” all the time, and what I’m looking for is to have it function as a home alarm that I can activate at my discretion. For example, only during the night, and during the day, it would allow me to have the door open (I hope you understand). ---

It is not silly at all. An alarm system basically depends on certain factors: - When is the alarm activated? (manually or via automations) - How is an alarm triggered? (i.e. motion sensors, door/window sensors) - How can you disarm it, just before it goes off - What does the alarm actually do? (noise, lights. notifications…) - How do you disarm it? - Also: What if guests, friends etc. enter the house? Can the alarm be remotely deactivated? This leaves a whole lot of logic issues and dependencies of devices. I am not too familiar with what Cube offers onboard. But I myself use Home Assistant for tasks of this complexity. I also integrated (smart) smoke detectors in the alarm system. All light go on, I get a notification. Just before it goes off, Alexa gives a warning though, that the alarm will go off in ten seconds if not deactivated - which you can do with either a code word or a specific button on a specific remote etc. ---

You can easily do it using Alexa smart speaker. Create a routine with the door sensor type as the action type(when this happens) and do whatever you want (add action). ---

Do not ask to know that time will tell you, that there is no prettier thing than knowing without asking hahaha. Who said that? A shameful and that I had a lot of time, but hey, after many years I learned that if another person knows, it is a law “if you want to” explain it to you. By the way I ignorant … I buy the IHOS why I say, I pass from Raspberry all day tuned and with errors, because I go three days that I carry … but I think the pot was bad — came without that emvolure that We like listening so much … ---
