Upgrading the z-wave-js addon from 0.9.0 to 0.10.0 using HA 2025.2.3 triggered the smoke detectors

[ha-reporting2023]

The upgrade process of z-wave-js addon from 0.9.0 to 0.10.0 using HA 2025.2.3 triggered the smoke detectors that are connected via z-wave.

Unexpected behavior that did not occur on all previous add-on upgrades until now.

So, don't go upgrading your z-wave-js addon late a night while the family or the neighbors are sleeping :-)

4 days later: received 3 x separate false smoke alert on the 3 connected smoke detectors at the same time.
That did not happen in the last 2.5 years since having these smoke detectors installed.
The Batteries are all + 85%

You may want to check the manufacturing date of your smoke detectors, as they all have a limited lifetime; and tend to get very noisy at the end of that service life. On the low end, a service life of 5 years from the date of manufacture can be expected regardless of brand/model. And at the maximum upper-end will be 10 year service life models; and will explicitly be marked as having such a lifetime. For all smoke detectors, the service life is based on the date of manufacture, not when they were first put into service in your home.

Additionally, the smarter (wifi, zigbee, z-wave, etc.) models tend to have a shorter service life than their stand-alone or basic hardwired/interconnected counterparts, which isn't great for smart home integration longevity.

As an aside, this is one reason why I'm using the Zooz ZEN55 smoke and co bridge to read from my required hard-wired smoke and co sensors. This means the detectors can be replaced as they age/expire either individually or collectively, without affecting my integration. One downside to this approach is that the integration is more of an all or nothing and can't be localize to a single room.

You mentioned that you've been using this integration for 2-1/2 years, so it's possible that a good portion of the service life took place before you installed these detectors. 2 years in a warehouse, or on a store shelf, is not uncommon, especially for more niche variations, like with zigbee or z-wave chips.
