2nd IR event handler doing the wrong action

[wenhuazhang2018]

in the summary, when there are more than 3 event handlers, the 2nd event handler for some reason will do the action of the last event handler instead of its own action.

• version: Built on Oct 6 2025 07:36:23 version 1.18.189
• Device Tuya IR blaster S18 chip CB3S
• Chip/model: BK7231N
• Device config?

this is the commands in startup:
"
startDriver IR
setFlag 1 1
addEventHandler2 IR_NEC 0xC7EA 0x17 backlog IRSend NEC 0x0 0xA8; IRSend NEC 0x0 0xA8; IRSend NEC 0x0 0xA8

addEventHandler2 IR_NEC 0xC7EA 0xF backlog IRSend NEC 0x0 0x8C; IRSend NEC 0x0 0x8C; IRSend NEC 0x0 0x8C;IRSend NEC 0x0 0x8C;IRSend NEC 0x0 0x8C

addEventHandler2 IR_NEC 0xC7EA 0x10 backlog IRSend NEC 0x0 0x9C; IRSend NEC 0x0 0x9C; IRSend NEC 0x0 0x9C;IRSend NEC 0x0 0x9C
"

when the device boot this is what happened:
"
Info:MAIN:Started IR.
Info:CMD:CMD_StartScript: started @startup at the beginning
Info:MAIN:Drv IR is already loaded.
Info:EVENT:CMD_AddEventHandler: added IR_NEC with cmd backlog IRSend NEC 0x0 0xA8; IRSend NEC 0x0 0xA8; IRSend NEC 0x0 0xA8
Info:EVENT:CMD_AddEventHandler: added IR_NEC with cmd backlog IRSend NEC 0x0 0x9C; IRSend NEC 0x0 0x9C; IRSend NEC 0x0 0x9C;IRSend NEC 0x0 0x9C
Info:EVENT:CMD_AddEventHandler: added IR_NEC with cmd backlog IRSend NEC 0x0 0x9C; IRSend NEC 0x0 0x9C; IRSend NEC 0x0 0x9C;IRSend NEC 0x0 0x9C
"

the 2nd event handler supposed send 0x8C when triggered, but instead it sent 0x9C (which is the action of the 3rd event handler). if there are 4 eventhandlers, the 2nd event handler will do the 4th event handler's action.

in the summary, the 2nd event handler for some reason will do the action of the last event handler instead of its own action.

Thanks for working on this, here is a update and clarification:

1. I rewrote the startup script:
   startDriver IR
   setFlag 1 1
   addEventHandler2 IR_NEC 0xC7EA 0x17 backlog delay_ms 50; IRSend NEC-0-A8-0-32

addEventHandler2 IR_NEC 0xC7EA 0xF backlog delay_ms 50; IRSend NEC-0-8C-0-32

addEventHandler2 IR_NEC 0xC7EA 0x10 backlog delay_ms 50; IRSend NEC-0-9C-0-32

2. during startup it appears fine:

Info:MAIN:Started IR.
Info:CMD:CMD_StartScript: started @startup at the beginning
Info:MAIN:Drv IR is already loaded.
Info:EVENT:CMD_AddEventHandler: added IR_NEC with cmd backlog delay_ms 50; IRSend NEC-0-A8-0-32
Info:EVENT:CMD_AddEventHandler: added IR_NEC with cmd backlog delay_ms 50; IRSend NEC-0-8C-0-32
Info:EVENT:CMD_AddEventHandler: added IR_NEC with cmd backlog delay_ms 50; IRSend NEC-0-9C-0-32
Info:CMD:LFS_ReadFile: failed to file autoexec.bat
Info:CMD:CMD_StartScript: failed to get file autoexec.bat
Info:MAIN:Main_Init_After_Delay done

3. but during testing:

Info:IR:IR IR_NEC 0xC7EA 0xF 0 (32 bits)
Info:EVENT:EventHandlers_FireEvent3: executing command backlog delay_ms 50; IRSend NEC-0-9C-0-32
Info:IR:Delay 100ms
Info:IR:IR send NEC-0-9C-0-32 protocol 7 addr 0x0 cmd 0x9C repeats 0 bits override 50

As you can see: 0xF event should send 8C, but it sent 9C instead.

4. I reboot and test it multiple times, on rare occasions it tested fine, but in >90% case the above error will happen
