    SwamCam Review | Pool Alarm - 3 Months In

    I think the biggest challenge is probably "remembering to use it" because, unlike us, they are only going to have it on when my daughter (and just found out we have a son on the way!) is at their house. Because its usage is only about once a week, they don't want to have the keypad or a cheap...

    Pool and spa safety alarm that does not require drilling

    This thread just popped up in "similar threads" while responding to a question about our SwamCam (which is also ASTM certified), in case anyone is looking in the future: SwamCam Review | Pool Alarm - 3 Months In

    SwamCam Review | Pool Alarm - 3 Months In

    Yes, I would strongly recommend it. In fact, I bought one for my parents' house. I'm big into complex home automations so I would be all for using Ring/Frigate or a number of others, but there is one key upside to SwamCam verses that make it better suited to a pool alarm: ONE local device does...

    Pentair IntelliCenter Pool Control Dashboard Instructional Guide

    I have an issue open on GitHub for a few months but my question here is just solving the symptom of the issue - any easy way to modify a file to tell it this light "sequence in progress" is no longer the current state of Intellicenter? I can control the lights only through intellicenter because...

    Feature Request: Why don't pump controllers dynamically set RPM for heating with solar panels

    All I've been saying from the beginning is that it cannot (and in my direct experience, does not) make any appreciable difference in delivered heat to run flow lower when the BTUs available are lower (assuming they can properly run that speed) - because the very same methods of heat transfer and...

    Feature Request: Why don't pump controllers dynamically set RPM for heating with solar panels

    Since you've mentioned this a couple times and it's a good point, wanted to add my experience here - I can run my solar all the way down to 900 RPM and still get flow at low pressures with my heater bypass on, but my VRV opens up at about 25gpm for the spa and 35gpm for the pool, so I just have...

    Feature Request: Why don't pump controllers dynamically set RPM for heating with solar panels

    This is literally all I am saying @Dirk - they are necessarily inversely related IN the heat transfer formula itself. In order to argue that anyone is wasting electricity and leaving a bunch of heat on the table due to slow flow in the morning vs medium (much less your inaccurate 21 minutes...

    Feature Request: Why don't pump controllers dynamically set RPM for heating with solar panels

    Exactly my point!! I'm not saying I'm getting more heat transfer, I'm saying I'm spending less to get roughly the same heat transfer. The math supports this all around. The effect of ΔT on heat lost through radiation (the only way heat is lost from the panels to the pool) is to the FOURTH power...

    Feature Request: Why don't pump controllers dynamically set RPM for heating with solar panels

    The thing is, insisting that volume is way more important than ΔT demonstrates you're simply not understanding the application of heat transfer formulas and what they mean for solar panels. Let me take a step back and try to demonstrate this concept in two different ways that you will hopefully...

    Feature Request: Why don't pump controllers dynamically set RPM for heating with solar panels

    Respectfully, I do understand the physics @Dirk, but you're entirely misunderstanding and thus misrepresenting my actual claim. I'm NOT talking about running the pump slower to get more heat. I'm simply not, so please reconsider what I am suggesting because we actually seem to somehow completely...

    Feature Request: Why don't pump controllers dynamically set RPM for heating with solar panels

    I just meant that I put another 1/2" NPT tee when I did my heater bypass and acid pump. Intellicenter has 3 sets of 10k ohm terminals for air/solar/water. I'm using air/water since solar is shot, but you can easily add more sensors to njsPC directly. My setup is actually very basic given what...

    Feature Request: Why don't pump controllers dynamically set RPM for heating with solar panels

    This is true in reverse too though, right? The manufacturer is providing that flow range for their rated BTUs which are at the highest temperature differentials. However, if the TDs are already low enough to maximize this efficiency such that it would be a diminishing return to run the pump any...

    SwamCam Review | Pool Alarm - 3 Months In

    I strongly considered just adding another Ring camera along this same thought process! But I didn't see a way to set up an "arm/disarm" function with loud indoor/outdoor alarm the way I'd really prefer. I also frankly expected SwamCam to live up to its claim alerting only for humans whereas...

    SwamCam Review | Pool Alarm - 3 Months In

    I had a heck of a time finding an alarm people were really happy with here so I figured I'd share our overall very positive experience with SwamCam. Some key takeaways: Phenomenal American-based support team that spent a whole lot of time on the phone and via email assisting with install and...

    Low Budget DIY Automation

    Agreed... I'm actually using nodejsPC now - very very happy with it as everything intellicenter SHOULD have been. Since the tablet stays on the wall, I set up Alexa integrations through nodejs via Tasker and Auto Voice. Also overlayed volume controls for the amplifier/chromecast and the pool...

    Can't lower PH

    I would lower your TA to 70 or even 60 if that's not quite enough - and see if your ph is more stable in the high 7s. For our purposes, within the typical 7-8.2 testing range, the exact ph number is mostly just relevant to calculate your LSI/CSI to prevent corrosion/scaling. The idea that ph in...

    $100 "Poor Man's" Acid Injection / Acid Pump

    This has worked great so next, I'm trying to experiment with Chem Doser. However, I'm wondering if I should just let it dose throughout the day and not worry about the SWG if it's truly a 0.3ph drop max? I measured 0.2ph drop at the returns at 22gpm, but I think the math also confirms this: I...

    $100 "Poor Man's" Acid Injection / Acid Pump

    Couple small updates: Vent tube out and up high off a resin shed where some pretty good breeze tends to come by. This seem ok? Tied the acid pump relay power to the load side of the pool relay and split off the SWG similarly, to schedule the SWG with no power when the acid pump is running...

    I was going to do a replay and checked "Capture Reconfiguration" - stuck at 13% even without touching my pump speeds. Happen to have a suggestion for me to get this back synced up?

    $100 "Poor Man's" Acid Injection / Acid Pump

    Really appreciate all of the counsel as I'm embarrassed to admit I just didn't know any of this! The reason I got this particular pump is because at ~1.5ml/min, it would be only a little over the 100% setting listed in the intelliph's manual i.e. 60ml/hr which is around 2oz to this one's 3oz...
