How old are your smoke detectors. If they’re not that old, how close did you position the firefighter devices to each detector?
I have one of these devices but I don’t need to use it as a temp sensor. If the device itself has a parameter to adjust how often it sends a temp update, then try changing the driver to the basic z-wave tweaker temporarily, change the parameter you’re interested in, and then change back to the firefighter driver.
Edit: also, are you in the US? The firefighter relies on the standardized tone pattern and frequency that smoke and CO detectors make in the US. I believe it’s a UL standard, and TBH I have no idea if that applies to devices sold in other parts of the world.
