IOT, will need a web interface and must have SNMP management too. May as well put a screen and browser on it too.

Those solenoid door bells normally use up almost all of the power from those class 2 transformers. -----Original Message----- From: [email protected] Sent: Tuesday, September 6, 2022 9:57 AM To: 'AnimalFarm Microwave Users Group' Subject: Re: [AFMUG] OT: Electronic question I'm thinking V=IR so if I add resistance to the newer bell would it draw more current and trigger the solenoid? Or would the resistor just be turning current into heat? -----Original Message----- From: AF <[email protected]> On Behalf Of Chris Fabien Sent: Tuesday, September 06, 2022 11:41 AM To: AnimalFarm Microwave Users Group <[email protected]> Subject: Re: [AFMUG] OT: Electronic question I think you are correct about the cause of the issue, probably the easiest solution is to leave the buzzer in the main circuit, and wire a 24vac relay in parallel with it, using the relay contacts to close and open the circuit to the ding-dong bell.
