Can I pair an Apex A3 Jr with an EB4 energy bar? I only have a 40B, and I just want some basic monitoring and to add some redundancy to things like my heater and ATO. I'm also thinking of adding some quality-of-life features like turning on and off my return pump and sump lights would be nice too. Is this a decent plan? The A3 and A3 pro just seem excessive for my needs. Thanks all!
