My ZHA Zigbee network worked but appeared to use an unsecured key, so anyone could access it which is of course a no go. Setting a key inside configuration.yaml didn’t work.
To get a secure network I decided to remove everything related to Zigbee and start over. I removed the ZHA integration and manually deleted the zigbee.db file.
Now adding the SLZB-07p7 controller back doesn’t work at all. It is discovered by HA, but installation fails:
Discovered:
SMLIGHT SLZB-07p7 - Zigbee Home Automation
→ ADD
Zigbee Home Automation
Do you want to set up SMLIGHT SLZB-07p7?
→ SUBMIT
Zigbee Home Automation
Failed to probe the USB device
I tried to add it manually, each time I get a “Failed to connect”.
I also tried to update the firmware using multiple computer: it either doesnt work at all or fails.
Is there someone that was able to reset its ZHA integration? Or anyone that could recommend a Zigbee integration that works with a secure network?
I had warnings about the key being insecure in the log. The messages were related to a previous Zigbee2MQTT installation. As I didn’t find any way to get ZHA to display the key it used, I looked into the system files and indeed inside zigbee.db in the network_backups table there is an entry with the network_key that is not random.
It was enough for me, I want my network to be secure and it’s easier to reset it now than later with more devices.
I am not sure you can, I did find very few information on ZHA security. I only found this draft in the zigpy repository in which it appears that you can define this key (some posts suggested to reset the integration for the key to be taken into account):
It worked until this reset, I thought the SLZB-07p7 was officially supported like the SLZB-07, but I doesn’t look like it.
