I have ordered a blue puck to measure temperature via Bluetooth.
Are there also devices to measure fluid levels in a tank, like a water tank, fuel tank etc? I know teltonika works with two vendors but those require drilling holes into a tank and to insert a rod to measure the levels. For me this is not possible as my tanks cannot be accessed from the top. So I need a device like the gobies pro - which is very expensive.
Thanks, Simon
