esp32 zigbee onLightChange unwanted results

[ilker-aktuna]

I am using Arduino zigbee library and ZigbeeDimmableLight profile for a simple device which requires level and on/off commands.
The device is configured as:
ZigbeeDimmableLight zbDimmableLight = ZigbeeDimmableLight(ZIGBEE_LIGHT_ENDPOINT);
And for the level/on/off devices I use the following method:

  zbDimmableLight.onLightChange(setLight);

void setLight(bool state, uint8_t level) {
  Serial.println("state:");
  Serial.println(state);
  Serial.println("level:");
  Serial.println(level);
}

I use Hubitat as my Zigbee controller and I send zigbee on / off commands as:

off:
[he cmd 0x0C0F 0x0A 0x0006 0x00 {0x0A}, delay 2000]
on:
[he cmd 0x0C0F 0x0A 0x0006 0x01 {0x0A}, delay 2000]

the device id is 0A and the hub sends 00 or 01 commands to the 0x0006 cluster.
That's the only command it sends. It does not send any level command.

However, on serial monitor , I see the following output for on and off commads:

off:
state : 1
level: 0
state: 0
level: 0

on:
state : 1
level: 0
state: 1
level: 255

So the esp32 zigbee library adds unwanted commands.
When there is no level command sent from the hub, it changes the levels. And additionally it sends unwanted state commands (2 instead of 1) so I can't act according to the received command.
Why is this happening ?

@P-R-O-C-H-Y , maybe you can comment...

thanks.

Hi @ilker-aktuna, if I get it correctly when setting to OFF you receive those 2 commands:
state : 1, level: 0 + state: 0, level: 0

when setting to ON you receive this:
state : 1, level: 0 + state: 1, level: 255

Is that correct?

[ilker-aktuna]

yes, exactly.
so why is that ?

That's how Zigbee communication works. It's always sending level + state. And as its 2 separate messages its triggering twice the onLightChanged. So you need to check both state and level. If state is 0 keep light off whatever level is. If state is 1, check the level.
