Interested in making these my control my lights about daytripper HOT 10 OPEN

Thanks, the relevant code is around here in the RX firmware. received_data[0] is the unique ID, you can check that and do your stuff.

If you're unfamiliar with STM32 dev, I have wrote a tutorial about it too.

You sure can keep it plugged in all the time, you don't even need the battery if you do that. As for controlling the lights, you can take a look at executing custom action.

Either an IFTTT Webhook or a Python script such as WeMo.py should work.

Interested in that too. Thanks for answering the "keep plugged in" question, that was also my first one.

Second, can you use (and purchase) multiple TX with a single RX, so that you can use one RX "base station" to handle multiple doors?

I touched upon this topic in advanced usage guide .

Basically, daytripper wasn't really designed with multiple TX or RX in mind, so I haven't done much testing. However Single RX multiple TX does seem to work, and RX will respond when ANY TX triggers.

And if you do want to buy a single RX and multiple TX, we can arrange what as well.

Thanks! When one of multipe TX triggers, can the RX figure out which one it was?

At the moment no. RX will do the same thing if any of the multiple TX triggers.

However, each TX does include a unique ID in its on-air-packet. So if you're willing to do a bit programming, it is completely possible to assign different actions to different TXs.

RX also prints out debug information in its debug serial harder, so that's another way to tell.

That's great, that'll do.

I've ordered one just now to try it out.

Good stuff, very appreaciated!

That's how modern hardware should work: Easy to order, easy to modify for your needs. 👍

I have a simmilar project, which may be possible with the daytripper.
For years i wanted to build something, that pauses the movie i am watching when i leave the room, and resumes it when i am back (i use kodi as a media center on a raspberry pi). The main problem here is if there are more than just me in the room and another person leaves the room it would resume the movie. So i would need something that can detect the direction of the person crossing the laser, for which i would need two lasers. With the ID you mention it may be possible for me to use two TX und figure out which one got activated first to determin the direction
