I have a 2 speed pool pump, selectable High Off Low.
I’d like to set it up so I could:
Run on Low via a schedule, ex: 6a-6p.
Select High automatically if the outside temperature is below 40*F
Select High manually to backwash the filter
Notify if the pump is supposed to be running but not drawing any power (pump fail)
Notify if power to pump is lost
I am new to Home Assistant, still waiting for my HA Yellow to be delivered. What would be the recommended hardware to accomplish what I’m trying to do? Pump is about 35’ from the back of my house. WiFi, ZWave, Zigbee? WiFi signal is ok in that spot, could be better. I plan to add a temp sensor for the pool temp as well. We also have a LED rope light around the pool that I plan to control with WLED or similar.
Apart from how you will connect between HA & the pump: what are the options to control the pump?
I mean, how do you control the speed currently and is there a possibility already to interact with that process?
Ok. Thank you. I don’t mind opening the cover and wiring relays to the switch. I looked at the Shelly Plus 2PM but it only support 8a on each output. My pump says 10.5a on high.
Owkay, if you can connect to the internal wiring with a relay it becomes easier.
If you are not using zigbee or z-wave yet but probably have WiFi, I would look for an ESPHome ready/capable relay but maybe someone else might have another/better idea.
Thank you. I appreciate your help. I saw one of the Shelly Pro models covers the amps needed for the motor. I’ll check with them to see if it will work for a motor.
You will need 2 relays since you have 3 states: on, off and speed.
Also, have a look at these threads:
Particularly the parts about the current for starting an electrical motor.
One more thing: you have to make sure that the relay you will be using can give you the power-draw so you can detect the pump fail.
