This plugin generated a warning

[MF-Bra]

With the latest version of home bridge I started to have these warnings

[homebridge-isy] This plugin generated a warning from the characteristic 'Firmware Revision': characteristic was supplied illegal value: number instead of string, supplying illegal values will throw errors in the future. See https://git.io/JtMGR for more info.
