Hello, I am trying to make a home security alarm but I am new to Node-Red. When the PIR has detected something i want it to send me a text on my mobile phone and a small led and siren should jump on when movement is detected. Now I am stuck at the part where i want the siren and led to jump on unt…

First you need to decide on a hardware platform.

I am currently using the Raspberry Pi 3 B+

And do you plan to use that to provide the hardware platform for the light and sounder? If so, you should search for people who have already added such things to Node-RED. There are examples around.

Well, i have looked around a bit but i didnt really find anything. At the moment my program is working fine, when the PIR detects something, the siren makes sound and the led gives light. But that is only for a short amount of time (± 2 seconds) is it possible to keep it on untill i turn it back of…

You've not told us what siren you are using or what your flow looks like.

Put a Switch node in before the dashboard items so that your existing message can only switch the led and siren on not off. Only send On messages (whatever they are) to o/p 1 and ignore any others. Then from your acknowledge button feed the Off message to the led and siren. The result is that the…

i also was looking for somthing like this , i ended up twiking my flow and used the below Node it really helped me , i am doing somthing real simple MP3 File on my PC (used for sirene) and all PIRs go to counter if the counter is more than two in less than 10 secs i get a notification on my pho…

You might want to take a look at this project I created for my IoT students. I reckon you could modify it to match your needs. It uses a Wemos D1 Mini to handle the IR side of things and then send an MQTT message to RPi-3+ running Node-RED. I've used Telegram to send messages to my mobile phone a…

This is excactly what i need, could you get a little more specific into the programming in node-red?

I suppose I'd better say this as nobody else has. It is easy to get carried away with things like this as Node-RED, Pi's, ESP's, etc make everything so easy to do. I certainly happily get carried away. However, there is a big difference between doing something for the fun of it and relying on some…
