Automatic Timer

We use liquid chlorine and acid to balance our water. Currently we have a Stenner Pump on a Grasslin GM40AVE timer for our chlorine and are looking to add a pump and timer for our acid too. I already have another Stenner Pump but am trying to find an automatic digital timer that can control two different pumps at different times. Does anyone know of one that does that, or have a similar setup? Worse comes to worse I will just duplicate the setup I have have now, but it would be nice to only have one timer feeding two outlets and two pumps (running at different times).

I use the SONOFF 4CHR3PRO

It has 4 different channels, that can be used with built in SW timers or even timers built into Google Assistant or Alexa.
Its also only $22 as compared to $200 :)

I've been using these things for ALL SORTS of automation projects including replacing my JANDY Aqualink pool equipment control center.

When we installed our pool we didn't have access to the internet so I never even thought about a timer that I could control from my phone and while away. We now have Fiber Optic internet and being able to control this from my phone and Google Assistant would be a great feature and it seems like the SONOFF does everything I would need it to. I'm curious how you installed it. I would have to install it outside in the elements somehow. I don't have room in the bottom of my subpanel, but could perhaps find another subpanel box to install it into? Not sure I could get it weather proof though.

@Rancho Cost-a-Lotta is correct! SPOILER ALERT --- I reused my old mental Jandy Aqualink enclosure that was already on the wall. I think any dust/splash resistant (IP65?), rainproof outdoor enclosure would work though. Might be worth oversizing it in case you need more room in the future ..... hint: I'm out of space in mine!

Maybe something like this?

I like that it has a door; sometimes its nice to simply be able to open the door and manually push the buttons to turn things on/off when you're working on the pool equipment, instead of having to whip out your phone. Also easier for shared use when others don't want to install the app.

After doing some more research I think something like what Skola has would work but I think I am overthinking it. I'm going to do a test this year with a Kasa outdoor smart plug. It has two plugs and each is individually controlled in their app. It's 16 bucks on Amazon and won't require any hard wiring or another bulky timer. If it works great, if not then I will explore adding something like Skola has.

That looks perfect! Especially if your pumps already have US power plugs on them.

Another alternative (I also use these for a few outdoor fountains) is the Wyze Outdoor plugs:

$10.99, and they work with Google Assistant as well (just like KASA).
