Description
Cheers, I was made aware of this app by a NUT community member and posted a link at https://github.com/networkupstools/nut/wiki/Android-clients (will add to proper docs later).
Looks great upon first impression, so please don't take this post as criticism but rather as points of improvement :)
One thing that I stumbled upon in a local setup was that I selected the "NUT" option as the server protocol and initially entered just the IP address (hoping to see the list of one or more UPSes exposed there, to select one). Alas, nothing appeared and the full devicename@servername had to be typed (as suggested in help text for the field). Fetching a list of devices and configuring them in clickety-click style would be a welcome addition. Likewise, discovering a server in the subnet which listens on expected port (and/or using mDNS/avahi if user's NUT is built with that) could be a further friendly option.
Another was that actually my first try was the hostname (which goes to IPv6 for me), and whether due to app or Android or networking concerns, it did not go well. UPDATE: After some investigation, I found that my upsd was actually only listening on IPv4. When I fixed that (adding a LISTEN myIPV6hostname along with LISTEN * for IPv4), the app picked it up well - so both DNS and IPv4/IPv6 are supported properly.
Finally, the issue because of which I came to post here: I had to explicitly enter the port number (3493). Although the help text speaks about default ports for different protocols, I somehow expected that an absent entry would cause the app to use that default port. This did not happen and feels like a bug :)
PS: not "remove server" but "remote server" in some message, and "18 of load" (missing "%" char) caught my eye ;)
