I just switched to the SLZB-06. I placed it in the middle of all Zigbee devices to a power connector and it is working over Wifi. Coming from an odd TI CC2531 that was crashing every 24 hours, doing software updates, change to the Sky Connect, that was not working with 5 of my 6 Tuya Plugs, reusing the CC2531 for them an booting the HA Pi every 24 hours.

Now everything works fine with the SLZB-06. The setup was fast and flawless, the Zigbee devices forming a better network and the Philips bluetooth bulbs not described as zigbee devices are working over zigbee with it.
