[murrayma]

The accepted convention for representing manufacturer and product identifiers appears to use hexadecimal.

My 2C.

I would also add some padding here, to remain consistent padStart(4, '0')

const deviceConfig = zwaveNode.deviceConfig || {
   label: 'Unknown product 0x' + parseInt(zwaveNode.productId).toString(16).padStart(4, '0'),
   description: 'Unknown type 0x' + parseInt(zwaveNode.productType).toString(16).padStart(4, '0'),
   manufacturer: 'Unknown manufacturer 0x' + parseInt(zwaveNode.manufacturerId).toString(16).padStart(4, '0')
 }

@robertsLando,
not sure if the padded format is used in the UI?

Thank you for the suggestion. I found an existing method, utils.num2hex() meant for this purpose and updated.

[robertsLando]

I already evaluate this values later here. I suggest you to move that at the start of initNode function and use the values from the array. Also remember to use zwaveNnode instead of node
