This is what I was able to do so far.

@isoeek Remove the loop inside the If/do as it not needed

@ajb2k3 LOL! Thank you. I completely missed that.

What motor module are you using?
I did some test of the earth unit last night and found out that if water raises above the black line, the unit will constantly read 1 in digital mode. Had some code issues with UIFlow last night and need to find my cap sensors

motor module
No worries on the cap sensor. It works reliable with analog and a low threshold. I'm using a DC diaphragm water pump that I'll be running with a mosfet speed controller. Here is where I got to last night.
I need to add a speed controller and a SSR relay...I feel like I'm forgetting something. Last night was not a good night for productivity nor thinking. Sorry.

@isoeek I know that feeling too well. Unfortunately the M5Stack SSR is not very powerful unless you get the ACSSR but you will still be limited on current

I'm sorry to hear you know the feeling. I have a few decent SSR lying around. I would have just bought the ACSSR if I would have known they existed. They are probably better than what I have and would have made integration easier. I'm only running 6A 120V AC, this is split to a 2A and 4A circuit. Thanks again for providing guidance and support as I figure this out.
Would you mind making a suggestion for resistors for M5stack. I keep seeing mention off them and know it will only be a matter of time before I need them, and I hate to not be prepared.

Suggesting a resistor is not as simple as it sound as it depends on the initial current draw of the device.
I blew the fuse in the SSR unit three times before I stopped to check the initial current draw. While the Heatplate (in my case) did use less then the SSR's nominal current, on initial power on, the heat plate would draw 3 times the current rating of the SSR's switch current rating!
Thankfully M5Stack placed a fuse on the the supply side to protect the SSR but I have yet to calculate what resistor I actually need for this scenario and hence the project went on hold.

@ajb2k3 Oh, I was afraid it would be in depth. Thank you, I'll read through it.
