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?

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.

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.
