Would it be possible to allow garadget to use a hostname instead of a ip for the mqtt server? I occasionally redo some of my servers setup and have to reset up my garadget because the ip of my mqtt server changes. I tried to put in a hostname in the setup of garadget but it only allows IP addresses.
It would be possible, but would require DNS client running on Garadget and DNS server in your network or other name resolution mechanism (NIS, LDAP or Active Directory). At this point it is not on the todo list, but the source is open so anybody capable and willing is welcome to modify the firmware as they see fit.
