Bitron 902010/24 #
Model | 902010/24 |
Vendor | Bitron |
Description | Optical smoke detector (hardware version v1) |
Exposes | smoke, battery_low, tamper, linkquality |
Picture | ![]() |
Notes #
Activating the alert #
Activating the alert is done by sending a JSON
{"warning":{"duration":1,"mode":"burglar","strobe":false,"level":"high"}}
This gives an audible alert with the LED flashing of around 2 seconds duration.
If you set strobe to true it’ll not work. Level “low” does not give a sound, the other valid levels don’t make a difference in loudness. There doesn’t not seem to be a difference between different modes.
The device seems to be a little bit picky about switching off - set both “mode”:”none” and “duration”:1 - but to another value than before.
Exposes #
Smoke (binary) #
Indicates whether the device detected smoke.
Value can be found in the published state on the smoke

Value can be found in the published state on the linkquality
property.
It’s not possible to read (/get
) or write (/set
