Thanks for testing it!
One note about the generator is that you do not necessarily need it. Electrical entities spawned via the plugin automatically generate their own power, unless they are plugged into another entity via mawire, very similar to how the Powerless Electronics plugin works.
How it works is that as the plugin or profile loads, electrical entities will initially spawn with power, then after they have all spawned, the connections that were previously persisted via mawire will be reconnected which may alter the power flow. If you have not plugged in the receiver's input, and you connect its output to the light, the receiver would have free power, and will only output that power to the light if it detects the RF signal.
The On flag doesn't do anything for the RF entities. The Reserved8 flag will be set automatically when any entity receives power.
I will test out the green light with a server reboot to see what is going on there.
