I have been looking for a solution to monitor doors and windows and of the RF transmitters I have found locally, they only transmit when the door is opened. There is no signal then closed. You mentioned that it sends RF for open and close. Do you happen to know if the protocol itself indicates open/closed status as part of the message?

Thanks Shabaz,

I enjoyed your presentation and as usual I learned many new things.

Great post Shabaz. That was a pretty thorough write up of the tech and great examples of real world application.

Thanks.

Impressed for this complete, top-down, clear and understandable treat. I am using your posts as the methodology template for the pieces I am writing on the I2C protocol and experiments.

Very good post.

I did have one concern.

Given that the RF has a fair range, is it possible for these devices to interfere with each other if they are clustered say in different nearby apartments or houses?

When you get a lot of devices radiating at near the same frequency, you can get some very interesting local effects.

Looks like a good solution. Check back in 6 months to let us know if it meets your expectations.

Looks like an excellent system.

I agree that properly rated devices are important.

The RF69 chip info is here

The library is here.

RadioHead: RadioHead Packet Radio library for embedded microprocessors

I guess you'll need to adapt some double switches and use your own transmitter.

I'm surprised they have used 433Mhz as the band is getting a little overloaded nowdays ... hence 915Mhz is popular.
