@pixel I am currently adding support for this smoke sensor:
https://www.robbshop.nl/z-wave-rook-en-co-melder-met-sirenefunctie-robb-smarrt
Which is battery powered (3x CR123A), but the Siren can also be triggered manually (my ears still hurt from doing this test for your guys)…
Nice thing about this sensor is that it is also possible to link them, where if one of the alarms is triggered (smoke, heat or CO), a english voice prompt will indicate where the alarm is triggered.
