Missing device functionality when using Alexa

I've just started moving from ST to HE, and I've just added two bulbs. One is an Ikea RGB bulb (called Driveway Pole Light). The other is an Osram Lightify bulb (called Sink Light). Neither bulb is working quite right.

The Sink Light: Alexa will turn the Sink Light on and off and set the color to the color specified in the command. However, if I tell Alexa to set a level for the bulb, Alexa returns a “The sink light is not responding” message. I can correctly control the switch, the color and the brightness from a Hubitat dashboard.

Driveway Pole Light: Alexa will turn the Driveway Pole light on and off and will set the level. But when I tell Alexa to set the bulb to a specific color, Alexa issues the command but the color doesn’t change and I don’t get an error message. When I go into a dashboard, I see the option to select a color but any change is ignored there also.

So, I can use Alexa to turn one bulb on and off and set the color, but I cannot control the brightness level. I can use Alexa to turn the other bulb on and off and I can adjust the brightness but I cannot change the color.

I have removed and re-added both bulbs. I have also tried selecting other Types including Advanced Zigbee CT Bulb, Advanced Zigbee RGB Bulb, Advanced Zigbee RGBW Bulb and Generic to no avail. I have also searched this forum but haven’t found an answer.

Any ideas or suggestion for further troubleshooting are appreciated.

Do they work as expected from the device page?

I can change the level on the sink light from the Device page but I cannot change the color on the driveway light. When I try to, I see the following error in the device log:

errorjava.lang.NullPointerException: Cannot set property 'requestedHue' on null object on line 815 (method setColor)

I'm not sure what additional troubleshooting I can do.

The driveway pole light may be a range issue. Note the difference in device states between the two. It doesn't appear that the bulb and HE are fully talking to each other. You could try resetting the bulb and repairing in place (without removing it from HE) and seeing if the current states updates properly.

Is the Osram bulb RGB capable? Not directly familiar with them, but a quick Google search says they are just tunable white. If that's the case, you'll want to use the "CT" driver. I'm not sure that will fix your problem with Alexa though and I'm fully Google, so won't be much more help there.

Thanks for the suggestions. I found a DTH (which I think is just a type in Hubitat parlance) on Github that lets me control switch, level, color and also lets me use Alexa to control the bulb.
