    Featured Charcoal Chunks Coming Out Of Returns?

    From the article, not a dig, it's buried in there: "The simple solution to solve this problem is to find another less noble metal to use as a sacrificial anode that corrodes but doesn’t cause staining " Here's one on Amazon. Link Do NOT just throw a Zinc ring in your skimmer. It does nothing...

    Are there any Electrical Engineers on here?

    https://www.troublefreepool.com/threads/are-there-any-electrical-engineers-on-here.191031/post-1683319 I would check out the above link. Pretty sure @Rattus Suffocatus nailed the solution with this one as far as a framework goes.

    Biggest problem with TFP

    I can’t count the number of times I’ve looked out the kitchen window to see an empty SPA and ran out there thinking I’d set the valves wrong and drained it just to realize once I got out there that, nope, it’s still full of water. 3 years in and I occasionally still do it.

    It's probably the same as mine +/- an amp. Doesn't take very many amps to power the control panel and make a spark. It might also be printed on your transformer itself in the heater. But worse come worse, a 15amp breaker is what was probably on your Intermatic or whatever you had on there...

    WannaPool DIY Pool Automation Build Thread

    I leave my heater on and control it with the three-wire config. Not crazy at all. The other thing I found on my heater, but I suspect applies to all gas heaters is that high voltage scary 240V line that runs into the heater immediately gets introduced to a 240V -> 24V AC transformer the minute...

    Amazon Smile

    Well this is sort of pool related... Amazon Smile is now available in the phone app as well as the webpage. So you can support TFP even when you're buying from your phone...

    WannaPool DIY Pool Automation Build Thread

    I ran into this same problem. I ran as root for awhile, the project can be moved or the homedir for node-red changed. Eventually I found setcap which let me bind to port 80 from the pi account for the node executable. I had both of those Alexa nodes stop working towards the end of last year...

    PWM SWGs (Circupool 4th gens) and CYA

    I hear ya! This is my third season with my pool. Bought the house and having already learned about TFP methods in preparation I tested the CYA the day I got the keys... 200+ CYA!! Three nerve-racking pool drains later I promised myself to never have to do that again!

    pH sensors that don't have to be calibrated

    I don't think you'd need a true PLC to read it. The signal is sent on a 4-20mA signal. Without looking I believe the megaIO has one of those. The industrial board definitely does. Maybe not having a PLC in there would give you space for a 24V P/S?

    PWM SWGs (Circupool 4th gens) and CYA

    Well I'm definately bored! And just for anyone who comes along this thread and thinks I'm trying to change the methods of TFP as a whole, I'm certainly not and wouldn't dare. I'm just curious about this corner case for the few of us (well, and all of Austrailia) with the PWM SWGs and how it...

    PWM SWGs (Circupool 4th gens) and CYA

    Sadly, I've found that people who truly enjoy what they do are far and few. Luckily, as network engineers, we don't have that problem!

    EDGE40 here too. I just looked again, it was your thread on the EDGE40 that got me wondering about this. Good find!

    PWM SWGs (Circupool 4th gens) and CYA

    Thank you for the data point! I provide a link to @chem geek's original post in the first post and quote him. You remember it correctly. I'm hoping the EDGE is the gentle FC generation he speaks of. My pool is surrounded by 50 ft tall oaks. The way the sun travels, I only get direct...

    Actually, you've been very helpful! This is part of the info I was looking for. I will keep an eye on my FC and the power settings over time.

    PWM SWGs (Circupool 4th gens) and CYA

    I'm not looking to solve a problem per se which is why I posted this in the Deep End. I'm just curious why I would keep my CYA levels at SWG recommended levels when Chemgeek made the statement (and I'm partially inferring here), that since I have a lower power slower infusion of Chlorine into...

    PWM SWGs (Circupool 4th gens) and CYA

    Those aren't my words. They're from ChemGeeks post. I'm not talking about keeping an unmeasurable CYA just a CYA level that's more in line with non-SWG pools. The power supply driving the EDGE uses PWM on the DC side to modulate the DC power to the cell. It doesn't operate like a normal...

    PWM SWGs (Circupool 4th gens) and CYA

    From here, @chem geek said a long time ago the following: Salt Water chlorine Generation (SWG) pools seem to require a higher level of CYA, about 70-80 ppm, to operate efficiently. The theory is that the CYA is slow to "store" the chlorine as it is being generated so without enough CYA there is...

    Well THAT I understand! Pretty cost me an extra $150 when building my controller and it was worth every penny. I found some safety transformers that look like they'd fit the bill. Link

    Those specs look a lot like this unit on Amazon. You'd want a safety transformer for sure. Could you just repurpose the transformer you already have?

    1. Yep! If you haven't seen my youtube on the node-red side of my controller it's here and describes the scheduling I can do. You could also just use a simple inject node to kick a flow off 2. Yes. @Katodude is making use of these I know in his flows. You can store things in flow or global...

    My new automation system.

    Hi, thanks! The new board (MEGA-BAS) still hasn't been released. Very excited for it. For now one of the BurgessWorld ADC hats on Tindie would be the way to go if you don't want to build any circuits.

    Yet another DIY pool controller thread

    I ran across this nugget last night that I'd never thought of trying. @AllenA is tapping the PVC and putting threads in it. Might be a viable alternative to add an injection port without adding a T.

    IntelliCenter Home Automation Integration and Control

    Look at all that easily accesible DATA! That's a beautiful thing! I'd say you get the cookies! And kudos to @Katodude for lending a helping hand! Does the node-red flow work and toggle the pump? It was something I quickly whipped up so wasn't sure if it'd need some tweaks

    Stenner Pump Controller/Automation

    I must've read that wrong, I stand corrected! I'm convinced you can never have too much raspberry pi! The 4's are pretty susceptible to heat issues but for the most part, they'll just throttle. A pi 3B or Pi 0 would most likely run ok even in those hot AZ summers I miss so much. I tried...

    Stenner Pump Controller/Automation

    Man cannot live on one pi alone. :D If we're talking custom controller route this might do the trick for your compartment. Then you just communicate with it from another pi in your house using something like MQTT. There are also web controlled relays that you just send a GET request from a...

    Stenner Pump Controller/Automation

    I think I read it's the opposite. The three criteria are Pump is running, SWG is off, and the system is not in SPA mode.
