My house was previously multiple units, and has nice sounding chime doorbell for two floors. I’ve set up a relay board so family members can ring one or the other bell from HomeAssistant. If someone comes to the front door, I’d like them to press a button to ring both.
Obviously I can use a smart button and a simple automation to trigger two relays. But is there some way I’m overlooking to have a dumb, standard wired doorbell button that will ring both chimes without causing either relay to also ring both?
Maybe there’s a DPST weatherproof push button out there that would look nice on the wall?
It’s easy even without a DPST switch if the relays are SPDT (and many are)… Basically now the relays switch between nothing (upper contact, if present) and ON (lower contact). Make them switch between MANUAL and ON:
Oh nice, yes the relays are dual throw and I had forgotten to consider that!
