FYI, RaspBee can still be a problem for two reasons so my advice is to buy a new adapter regardless:
- RaspBee II is outdated hardware (and obsolete for new purchase) so while you might be using the latest released firmware that does not mean that it is new firmware because the RaspBee II as a product is end-of-life and the manufacturer has not been releasing firmware updates for it in several years. So do take note that the latest firmware was released on the 8th of June 2020 (08-Jun-2020) which is almost 4-years ago now:
- More importantly, the RaspBee II is an intern Zigbee Coordinator adapter/module which makes it much more susceptible to EMI/RMI/RMF interference compared to using an external Zigbee Coordinator USB adapter connected via a long (and shielded) USB extension cable so you can not get it away from sources of interference. Be sure to at least use wired Ethernet instead of WiFi and move away any USB 3.x devices from the RaspBerry Pi (i.e. use properly shielded USB cables and get those devices away from the Zigbee Coordinator). Again, the Zigbee Coordinator is extremely sensitive toEMI/RMI/RMF interference, so do read and try to follow all tips here:
My recommendation is to buy either “Home Assistant Skyconnect” or “Sonoff ZBDongle-P (by ITead)”:
- Home Assistant SkyConnect (Home Assistant Connect ZBT-1) - official Zigbee and/or Thread USB radio dongle from Nabu Casa
- ITead’s “Sonoff Zigbee 3.0 USB Dongle Plus V2” (model "ZBDongle-E") based on Silicon Labs EFR32MG21 +20dBm radio SoC/MCU
Just watch this to get a grasp how interference from USB 3.0 is literally killing Zigbee comminication :
