    WannaPool DIY Pool Automation Build Thread

    About 1/2 down this page There is a section called Interpret Commands and Room Awareness It figures out the SN of the Dot that you are talking to, and then you can route the response to that Dot. In my flow, I'm turning on the lights in the room where the Dot lives. The next example is a flow...

    Hacking Pools?

    I also use lastpass for generating long, random passwords. But for the security of my home network, I don't use port forwarding, and have my router locked down as much as possible. My Netgear router supports VPN, and I use the VPN Connect app to connect my phone to my network from outside...

    DIY Automation/Control ESP32

    Thanks for sharing Thanks for sharing I thought the interesting part of this project is you're using your own VFD to make a diy Variable Speed Pump. I saw somewhere there is an advantage to getting the VFD away from the heat and vibration of the pump. Be curious to see how that works for you...

    Any DIY PLC setups out there?

    I put in a stenner at the beginning of the year. I'm using an outdoor smart plug to turn it on and off, so daily dosage is time based. That's been working well. I just check chlorine once a week now, and its been fine every since I added the Stenner. I have been looking at methods to decide...

    Hanna Phep Digital pH Meter-Update

    I've been thinking about getting a ph meter, guess I'll avoid the cheap chinese ones. I did find that Hanna makes a HI98100 and HI98103. Both have removable tips. I'm reading conflicting information on the 98100 accuracy though, most places it says 0.2, but in one place on the Hanna website...

    Controlling Rs485 slave devices (heater, pump, SWG) directly with Pi

    I use a DS18b20 temp sensor, and install as described here Its not hard, but you do need a tap to do it like I did. Tapping plastic pipe is easy though. I would recommend making the hole at a joint where its thicker, not in the middle like I did. But, if I was starting now, I'd probably use...

    Controlling Rs485 slave devices (heater, pump, SWG) directly with Pi

    There is also a 2 wire mode, that just turns the heater on or off. You could monitor the temp, and turn it on until it reaches the temp you want. But more work to do it this way. Being able to pick two temps works fine for me.

    Controlling Rs485 slave devices (heater, pump, SWG) directly with Pi

    I have a Hayward heater for my spa, and a Hayward vsp for my pool I control both with relays. The heater has a 2 wire and 3 wire remote control mode. I use the 3 wire mode. Two relays. You short the common wire to one input to go into pool mode, and the other input to go into spa mode. Only...

    DIY Automation/Control ESP32

    If I wanted to light those 12V leds, I'd google for a simple transistor circuit driven by arduino or pi or esp. It should take a transistor and a few resistors per LED, but you also obviously need a 12VDC power supply. Since the ESP32 has a bunch of GPIO, you can dedicate 8 GPIOs to drive the...

    automatic dosing

    That may be a reason to not diy both a chlorine and acid dosing system. I dose chlorine, and my fiberglass pool doesn't require enough acid to add an acid doser. I trust software about 95% of the time, so I wouldn't depend on sw for the interlock. It can be done in hardware, but would take a...

    automatic dosing

    Maybe the system is smart enough, or has some kind of interlock where only one of the pumps can run at a time. So it won't let you inject chlorine and acid at the same time, and avoid your concern. Since its a combined system, that would be pretty easy to do. Randy

    DIY Automation/Control ESP32

    I have a page about how I wired up my pool equipment here Another page on setting up ESPs Both links have a lot of subpages. I updated part of the ESP stuff recently, but some is out of date. The pool stuff is old, but that hasn't changed except for the temp sensor info, which was revised...

    DIY Automation/Control ESP32

    To wire up my ESP's, I used double or triple bases for the mini D1's link to bases from ali (I bought from a different store, just found this link in a quick search) But I don't see bases like that for the ESP32. Too bad, it really helped me. I always install a set of sockets in the base, so...

    DIY Automation/Control ESP32

    I use an ESP8266 to control my pool equipment with relays. I have a pi inside that tells the ESP what to do. They talk over MQTT. Actually have a couple pi's, one runs Home Assistant and the other one is running Node Red. Using Pi's and readily available software like this, its easy to make...

    Any Pool Automation Grafana / InfluxDB users out there?

    In Home Assistant, guys have figured out how to talk to Pentair EasyTouch systems too. Home Assistant Pentair This one requires MQTT. There might be other options that don't use MQTT if you don't have it.
