Hi - I have an off-grid shack in Australia with a Victron power setup including a Global Link 520. I would like to attach a water sensor (10k litres / 1.8m tall) to my tank (which is about 5-10m from the GL520) to alert me when I need to fill up my tank. Can anyone recommend a decent water tank sensor for this purpose? Thanks!
U have space under the tank? Then this is one supported option via Bluetooth

Sorry to disappoint you, but Mopeka Pro is not yet supported as a smart device for the GlobalLink 520.
Unfortunately there is currently no tank sensor supported by the GlobalLink 520.
The Bluetooth on the GlobalLink can be used to read data from (a select list) of Victron products. And it can be used to read data (temperature, humidity and air pressure) from the Ruuvitags. Nothing else.
Sorry James, missed that.
There is a list of data attributes that are sent to VRM (from where you can access the data) from all devices that can be connected to the GlobalLink via VE.Direct and BLE. Please see: https://www.victronenergy.com/media/pg/GlobalLink_520/en/appendix.html#UUID-5a4b7f79-dede-1b6a-0404-7fff6c689486
You can use a 3rd party water sensor with a relay output, and connect it to the digital input of the Globallink. Then you will get alarm when the digital input is triggered.

Anything with a relay works...
Just google "float switch sensor"
Example: https://uk.rs-online.com/web/c/automation-control-gear/sensors/float-switches/
It depends mostly on how easy or advanced/clean you want to install the sensor itself. This one is very easy... as it just floats on the top... once it goes vertical, it triggers: https://uk.rs-online.com/web/p/float-switches/1919492
Can be hung from the lid of the tank, no need to drill extra holes in the tank.

Hi James, we do water tank sensors with 2% of Full Scale repeatability. These are differential pressure with the air side of the sensor having a small tube encased in the electrical cable from the sensor. Your height is a special order. The sensor is 10-30V power and output is 0-5V DC. So if you put this into the AUX of a Smart Shunt you would read the voltage remotely and therefore translate as level. We do have a new product for 2023 (our own PCB) which reads Victron Bluetooth devices and shows values on a 55mm round touch display locally. Just google Safiery. Cheers
