Ideally I would like a tank gauge that can report tank water level to a home automation system.  I see some expensive options in NZ and USA.

I need something very simple that just can report the level periodically or when queried by the monitoring system.  WiFi comms. would be my 1st choice but other options are also reasonable.

 

If a remote monitoring option is too expensive or too troublesome, I'll just have to settle for a visual indicator of some sort.

 

Anyone have experience or recommendations?

 

It is called a pressure gauge. If you know the pressure, you know the depth. 10m=1 Bar.

Hardly usable for a 1000 or 2000 ltr. Tank.

A02YYUW water resistant ultrasonic sensor uses simple UART communication. Can use Wi-Fi of ESPXX or similar, lots of info kicking around for these devices.
