I recently got a pair of Zigbee 3.0 RGBW bulbs from AliExpress mostly because I wanted the E14 socket, the Zigbee protocol (also to be used as routers) and the low price (the Hue E14 are really expensive).
I am running HA on a RPi 4 and my Zigbee network is with ZHA and a Sonoff CC2531 coordinator.
I noticed that the bulbs are acting a bit awkward when using the sliders and the changing color wheel. They don’t respond to the colors I select and I have to move the brightness slider for them to change color.
Does anyone know if the firmware on such bulbs can be upgraded in hope of fixing such issues? Do I need a Tuya hub for this?
