Device: Ledvance P40S TW E14 bulb
If this light get a command to change brightness (or any other change) it first report the new state, then bounce back and report the old state and then a third report of the new state.
So to be more clear:
If this light have “40” brightness at start:
- Send command brightness “254” to light.
- In deCONZ events it first report brightness changed to “254”.
- Some millisecond later it reports the light have changed to brightness “40” (state before command sent).
- Some millisecond later it reports again brightness “254”.
No other brands like Hue, Ikea, Icasa etc. do like this. They only send one changed event after sent command.
My main issue for this is I have written a “dim-to-warm” function in Node-RED that works will all lights except Ledvance since it send out to many events just for 1 change/command.
But also when change brightness in GUI like HA, Phoscon, Google Home or HomeKit I actually see the slider “jumps” back and forth. No other lights do that.
