ok, but strange when you only use id in the script!
"For some reason" it is because inside the names are used sometimes instead of the id
"known issue" not for me
"Easy fix" yes after the diagnostic (1 hour) because I didn't jump on that conclusion immediately
I follow the forum a little bit and on the zwave2mqtt topic people are moving a lot of devices from OZW to zwave2mqtt having the same issues with double device names in dzVents. I must admit that your use case did not occur there.
As @waaren has sadly fallen away from us I hope someone can step up and fix this kind of dzVents issues.
Domoticz running on Udoo X86 (on Ubuntu)
Devices/plugins: ZigbeeforDomoticz (with Xiaomi, Ikea, Tuya devices), Nefit Easy, Midea Airco, Omnik Solar, Goodwe Solar
Yes, bad news for waaren
The duplicated names are not the fault of zwave2mqtt, but mine.
zwave2mqtt initiated the devices with unique names, but I didn't like them!
I renamed some of them manually with temporary names to better understand the devices, and so I've set lots of duplicated!
I need to change them...
