Apex question- voltage and probe

[cjcmcheek]

i have two questions regarding the apex.

i am looking for a 220v socket expansion if possible. does anyone have experience with using their 120v version?

also

is there any type of AIR temperature probe that is compatible with the apex?

I believe that the 220V expansion socket is discontinued, but a quick spot check of a couple of resellers shows them as still listed at Premium Aquatics: http://premiumaquatics.com/store/me...D&Store_Code=PA&Product_Code=NEP-SOCKEXP_220V

You can use a standard Apex temp probe to measure ambient temperature.

here is the million dollar question, is there a relative humidity sensor?

Not from Neptune but any humidity sensor that outputs via dry contact will work, like this one from Smarthome. You'll need the breakout box or DIY something equiv.

Do a search, there's a number of threads on this. I think Ken uses one that's a different brand but he's posted the link before.
