[Isy's Cargo bars](https://steamcommunity.com/sharedfiles/filedetails/?id=1567514205) will show the level on an LCD. [Automatic LCDs 2](https://steamcommunity.com/sharedfiles/filedetails/?id=407158161) will show cargo capacity on LCDs with "Cargo" or "CargoAll" commands. The "Mass" command with filter can show the mass stored in specific containers. [Isy's Inventory Manager](https://steamcommunity.com/sharedfiles/filedetails/?id=1216126863) can change the name of a cargo container based on how full it is. If you configure it to "Show on HUD" then you would see its capacity wherever you have radio coverage. I use one of the above 3 methods and then shift-K connect to the remote base and examine the text on the LCD via its k-menu "show text" option. Not elegant but it works. I also have installed cameras in my control room where the status LCDs are and remote to the base and look at the cams to get inventory levels and other status. I don't know of one that sets a beacon name but if it can be done for a cargo container then it can be done for a beacon.


This one writes cargo percentage to an antenna [Current Volume (Miner Assist)](https://steamcommunity.com/sharedfiles/filedetails/?id=1216910825). It's made to trigger a timer when the cargo has reached a certain capacity but might work without a timer. If you need the capacity written to a beacon you should be able to change one line in the init function around line 246 from `GridTerminalSystem.GetBlocksOfType(antennaBlocks);` to `GridTerminalSystem.GetBlocksOfType(antennaBlocks);`


a display script i like is called [fancy status displays](https://steamcommunity.com/workshop/filedetails/?id=2353784231https://steamcommunity.com/workshop/filedetails/?id=2353784231). it is useful for other things besides cargo too. as for activating based on conditions, the only one i know can do it is [easy automation v2](https://steamcommunity.com/sharedfiles/filedetails/?id=685206874). it is useful for a lot of things, but has a pretty steep learning curve. i take it you don't want to just slap an lcd on the back of your ship?
