You need to measure the depth of the tank.

Doing a search for float sensor found some hope that it is possible.

If your tank is deeper than 400cm (uncommon), this may not work for you. Part 2 will cover the Home Assistant integration of Hydrawise, valves, the ESPHome water tank sensor and automations for the entire garden irrigation setup.

However, if you want to receive notifications, track daily/weekly/monthly consumption, or add automation based on tank level, you must set up Home Assistant. I had the same idea, but was looking for also removing water (above ground when Im away and it rains) was looking at some things from Control By Web, I already use one of the devices for air/water temphttps://www.controlbyweb.com/applications/. water alarm sensor security detector doberman intrusion leakage protection level My water level maintenance consists of dropping a garden hose in the pool and letting it run for 30 minutes; I have to do this less than once a month. I've been working for quite a while on a simple & reliable monitoring solution for our garden cistern. Please remember that this subscription will not result in you receiving any e-mail from us about anything other than the restocking of this item. He explained that they are essentially just a toilet float arm attached to a valve and while they work great, in the event you have a leak you wouldn't know about it until your water bill arrives and is many hundreds of dollars.Fair enough. That is the minimum accuracy we can get. You will be redirected back to this guide once you sign in, and can then subscribe to this guide.

Tribus: A ratio of jump to vertical leaping ability, I had the same idea, but was looking for also removing water (above ground when Im away and it rains) was looking at some things from Control By Web, I already use one of the devices for air/water temp, I now have it "working" using two types of sensors. This works fine and would probably do what I need. You can follow our previous guide to install Home Assistant on Raspberry Pi or older laptop. This setup had way better reliability and no wifi connection problems. He is also a solo traveler who loves hiking and exploring new avenues. You can also use this sensor to monitor the level of the salt tank. The ultrasonic water level sensor works by sending sound waves of a certain frequency (also known as ultrasound) and receiving the reflected wave from the target object. Tried ultrasonics, don't work - after a while condensation screws it up. Conceptually this seems easy, but I need to find a sensor that can tell me the water level (or the delta from filled) and report that data out via wifi. I have an ultrasonic sensor to measure the level in a rainwater collection tank.

The ESPHome configuration for the water tank sensor is relativly simple. I read it with a KNX analog IO module but it should work with an esp too (put shunt resistor inline, measure voltage at both ends of resistor, quick maths and boom. However I'd suggest putting a "timer" on the water line so that if it is run for X it shuts off and sends an alert.
