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?
@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.

@tnick STM32F1 2019.12.8 (stm32duino) is the version that was active when the latest MySensors release was made. Later versions may or may not work; nobody would know until they tried.
@tbowmo are you still here man?so what is the pin? I also lost my PIN to d3 game controller and I want to get this connected to my phone to play, that's the third step and it won't connect unless I know the pin to this apparently.
I'm having the same / a simular issue of temperature related readings, but at a different temperature level (for me it must be > 14 degree). I massure the dew point as well (temperature = orange, dew point = yellow). It looks to be more related to water in the air than only to temperature.
@zboblamont have you been finally been able to find a solution?
