Does anyone have an alarm that can be used with HE to activate a small alram to chase the animals away.
Are you looking for a relay that can be controlled by hubitat to connect to a siren you already have? Or a siren controllable by hubitat? Little hard to tell what you mean by an alarm that can be used to activate a small alarm.
If you live near a Zoo Lion dung works a treat
Here is the list of official supported devices... many sirens to choose. All zwave tho

I actually do but they refrain from people asking for it.
Might be some inspiration from @jdjmailbox in his Garden Guard thread:
Depending what state you are in I'd be happy to come "chase" some away
If you were really dedicated, the state wouldn't matter.
Sure it would. Sometimes cost outweighs benefit.
