Apex - EB832 24vdc - IoT Relay

[Shon]

Planning 40b build. I'd like to get by with the 1x EB832.

Browsing/Buying parts for build at the moment and came across this product and thought that maybe using it will free up 3 controlled sockets.

*("Q: How much current does it take to trigger the control port?
A: About 0.2mA, the input is constant current. 12-120VAC or 3.3-48VDC will trigger the relay. DC trigger input is polarity sensitive.")*

Plug IoT Relay into 120v socket.
Unplug Heater, Chiller and Pump from EB832
Plug into IoT Relay
Use the 24vdc output from Apex to control the IoT relay.

Is this feasible?

Idea: Temperature Controller
-2 plug NO
1: Chiller (Cool to 77)
2: Pump
-2 plug NC
1: Inkbird + Heater (Heat to 77)
2:

If Temp < 76.0 Then ON
If Temp > 78.0 Then OFF

*If all temp monitors were accurate*

Searches only brought up Pi and Tunze ato results. Something tells me it's a bad idea if some one hasn't done it yet.

How about a generic wifi power strip. Does the same thing. I added one similar to the picture to pull a eb8 to use on another system. I use it on the items that don't have to exclusively rely on Apex switching like my sump powerhead, aquarium cam & auto feeder.

Sure that should work, once you fix your logic, or swap what's plugged in to the NO/NC plugs. When the IoT relay is triggered it will close the NO relays and open the NC relays.

You'll lose the high/low power draw feedback from the Apex so if your chiller pump, heater or chiller fails you'll have to catch it yourself.

I suspect that the reason you don't see a lot of people doing it this way is that adding an EB4 for more plugs isn't terribly expensive and there's no downside to it.
