Since you are already using a PubSub, why don’t you just broadcast from the first GenServer every second using a different topic and let whatever interested party subscribe to it.

If you have to do polling, I’d skip GenServer, timer, sending yourself a message, etc, in the poller altogether, and just spawn off a plain process that sleeps periodically.
