Hello!

I moving to a new home with a small pool and I was thinking of buying a pool sensor.

Right now I’m searching for something simple like temperature but would be nice to have ph and others.

I’d like it to be local, no cloud, and right now something cheap, I love DIY stuff.

So, any recommendations? Any experiences with these kind of sensors? My searches lead to pretty expensive stuff that can measure all the pool parameters and cloud based.

Thanks for reading!

    I built a pool water temp sensor using an ESP32 and a DS18B20. I drilled a hole in the pump intake pipe, installed it and now I always know the temp of the pool.

    I cant find the original page I used to build it but it wasnt hard and there are similar guides online. Here is the code I am using on the ESP32

    esphome: name: esp-pool-temp

    esp8266: board: esp01_1m

    Enable logging

    logger:

    Enable Home Assistant API

    api:

    ota: password: “fa053faa36e5d6600a5613086aaca3ca”

    wifi: ssid: <SSID> password: <password> fast_connect: true

    Enable fallback hotspot (captive portal) in case wifi connection fails

    ap:

    ssid: “Pool-Espboard Fallback Hotspot”

    password: “MCueN8HiEEvS”

    captive_portal:

    Example configuration entry

    dallas:

    Individual sensors

    • platform: wifi_signal name: “WiFi Signal” update_interval: 60s
