@jaydenlord Probably you do. If you leave the EN floating, electrical noise could cause it to enable or disable randomly.
Some enable pin require a HIGH, some LOW. Connect it to VCC to see if it works more consistently. If it doesn't detect, connect it to GND.
If one of these works, then the part wasn't designed to be in a default state of enable.
Let us know your results (I found this video

https://github.com/mysensors/MySensors/pull/1562 switches to using libgpiod instead of the earlier interface. I have not tested it myself but it looks good.
@mvader Turn the time delay adjustment preset on your PIR module to the minimum.. Now try it.. You will not get a continuous output..Also, prepare the circuit using a long wire from the back to the sensor of your module.
@Eme
Thank you for coming back to report how you solved your problem! Your comments will help other people.
I am a big fan of Frugal Tech and I think MySensors is great for that.
Alas, MySensors is not well supported anymore. Right now I'm having problems linking to the home page It's people like you and me that will keep MySensors going.
Thanks for your help.

You write "...clicking is heard..." Is that a single click or a click click click ...?
After getting the LOW signal, wait a period of time and if it's still low, send the message that there is a flame. Likewise for a HIGH signal.
Perhaps instead of a relay, an opto-isolator?
