Cannot turn off siren - Frient Intelligent smoke alarm (SMSZB-120)

[SvenNilsson]

Does the issue really belong here?

• I definitively want to report a bug within deCONZ or its REST-API

Is there already an existing issue for this?

• I have searched the existing issues and there is none for the bug at hand

Describe the bug

The Frient Intelligent smoke alarm should support setting 3 states via the rest apis on the "warning device" endpoint:

• https://ip-address-to-rest-plugin/api//lights//state.
• body { "alert": "select" } and { "alert": "lselect" } and { "alert": "none" }

select and lselect would turn on the siren and none should turn it off.

sending select and none does nothing. (sending lselect, turn on siren which has to be manually reset/turned off by pressing the button on the smoke alarm (front))

Steps to reproduce the behavior

use put command on endpoint:
https://ip-address-to-rest-plugin/api//lights//state

first with body: { "alert": "select" }, siren does not go off

then with body: { "alert": "lselect" } siren goes off

then with body { "alert": "none" } siren does not stop

Expected behavior

{ "alert": "none" } stops the siren
{ "alert": "select" } start the siren

Additional context

From what I could see reading the code the DDF have been changed lately (August 8) and actually tested with my device... So it could have something to do with this part of the DDF, if this issue didn't exist before:

{
"name": "attr/uniqueid"
},
{
"name": "state/alert",
"description": "Start warning command payload has 5 Bytes. Byte 1: Options. 0x17 = Warning mode 1 (burglar), Strobe, Very high sound. Byte 2-3: Duration, Byte 4: Strobe duty cycle, Byte 5: Strobe level",

For anybody reading this and have the same issues, using the previous ddf file solved the issue for me. Seems like this line introduces the bug: "eval": "if (Item.val=='select') { '1701000000' } else if (Item.val=='none') { '0000000000' }",
