Pool Automation help PLEASE

[careingemt]

Asking for advise / a direction to go with automating my pool currently running Home-Assistant. I would like to incorporate the following :
water tempature
pump control
flow switch (detects if pump is actually moving water)

Do you have a heater? What type of a pump do you have?

No heater , Hayward (1 speed)

For temperature monitoring, there are many options. I use the Sonoff TH-16 with DS18B20 probe to monitor temps and control my heater. The probe is installed a thermowell threaded into a tee-fitting. The Sonoff switch works with the eWelink app, Alexa, HA, Smart Things and others. Mine is connected to 120 volts.

Sonoff replaced the TH-16 with a better unit that now provides historical data. You'll need to order the probe separately. Here is the updated unit:

With a single-speed pump, control is pretty straightforward. You just need to find a Wifi switch/timer that will handle the amperage/voltage of your pump. Options are limited if the pump is over 1 hp and connected to 120 volts.

Not sure how to detect water flow.

Thats the biggest issue i have... (in-line) is the water temp the same as the actual pool water temperature when the pump is not running ?

Here is my flow switch (Flowing closed and not Flowing open ) i have a raspberry pi run a python script to obtain the status of the switch

Nope. Pump would need to be running if the probe is installed in the plumbing.

I have a camera on my pool with the return & skimmer in view so I can check to see if there’s flow. Maybe an option?
