Hi,

I have a BTicino K4027C shutter switch with level control that I have connected to a third-party Zigbee gateway and Home Assistant. The current firmware version is 44. According to https://developer.legrand.com/local-interoperability/#Compatible%20products this device should be of “Cloud type” NLLV.

I do not see NLLV in the list of firmware files on https://developer.legrand.com/production-firmware-download/, but searching through this forum I found that NLLV is mentioned in the chang log under NLL here: https://developer.legrand.com/forums/topic/recent-firmware-updates/

Is the firmware file for NLL (currently version 61) compatible with device of cloud type NLLV?

If not, where can I find the firmware for my BTicino K4027C shutter switch with level control of type NLLV?

Sorry if this is information is already documented and I missed it.

Thanks!

Hello Marco,

Indeed, the NLLV belongs to the NLLx family. So, you can use the NLL firmware to update your K4027C switch
