[RE-wrenches] Wireless relays

Recently there was a discussion about remotely controlled contactors to
shed PV during generator operation I believe. I have a little bit of a
different need for remote relays. I need to remotely disconnect air
conditioning 24 volt control circuits using the dry contacts in the Enphase
smart controller. In other words, I want to shed air conditioning loads
when the system goes off grid and selectively turn them back on using the
logic in the smart controller. So what I would need is something that
detects a disconnection of the dry contacts and then sends a wireless
signal to disconnect the 24 volt control circuit at the remote location in
Normally I would just hardwire this, but it is not an option in this case.
Does anyone know of an elegant and cost effective way to accomplish this?
