Esphome with watermeter + relais + door sensor?

Hi I have installed esphome on a esp32 vroom c3 and installed a water meter yaml and connected a sensor , everything works perfectly but there are more pins that are not used, I want to connect 2 relais and a door sensor on it . But is it wise to do that becose the watermeter part is sending data every 2 a 3 seconds , don’t want to make things to difficult for the esp

Shall I put a second esp beside this one or shall I connect the extra parts and change the yaml and everything shall work ( if I do it right afcourse haha ) meby someone have tips?

With kind regards
Bob

One esp32 will be able to handle that just fine, even with the single core c3.

For Esp32 2seconds is a lifetime. Even for Esphome it means ~100 loop cycles. To handle two relays and a switch doesn’t really add any measurable processing load on your setup.
Just make sure to choose right relay-module. Esp32 is 3.3V device, so pick 3.3V relay module or 5V one that has high side trigger (usually jumpers for selection).
