The solenoid will not automatically create a new tile. New tiles show up when a new Module is connected (such as the EB832 or the 1Link modules you mentioned) because they introduce new outputs that the Apex had never seen before. But the solenoid is not a Module. It just plugs into an existing output on the EB832, 1Link, or FMM module.
Think of it like this…If you plug in a heater or a skimmer on your EnergyBar, that’s not creating a new output. You’re simply plugging into an output that already existed on that hosting module.
The 24v Accessory ports on the EB832 have default names of LinkA_#_9 and LinkB_#_10 where # is the AquaBus address of your EB832. If those tiles are not already on your dashboard, click the padlock icon to reveal the Unused Tiles window at the top of the screen and click to drag the needed tiles onto the dashboard. You can rename the appropriate output to Solenoid so it’s easier to identify.
You can also use the System View to see the names of your existing outputs on each module. In my example below, the 24v Accessory ports (9 and 10) on my EB832 are named SPS_PMUP and EB_GRO:
