I have a supposedly Matter compatible RGBW light bulb, that I can pair by first commissioning with Alexa and creating a setup code for Hubitat. Entering the setup code in Hubitat, it pairs as a Third Reality Matter Multi-Function Night Light (it's a Tuya device per my router). After pairing, I can send it one command, and that command works.
But after that, the device shows offline status in Matter details. It also becomes uncontrollable by Alexa. I can still ping it from the hub, however.
Should I conclude that this device has a Matter issue, or is there something else I can try troubleshooting?
The device is this one
