Hi there,


Ok that's interesting that you've got it to work with HA, which is key for me going forward with any home smart tech. Did that take much work to integrate?


Secondly, does anyone have a guide as to how much this system costs to have?


Thanks


Paul

Another option if you're using HA and dont want the cost of oilpal and a cloud service. Depends on if you have wifi near your tank but you can use an ESP32 board and ultrasonic sensor (suitable for outdoors) for < €20. Works very reliably. 3 jumper wires and a bit of preconfigured code to cut / paste. No big hassle to setup if you've already got HA going.

Amazing, thank you. I assume that board as WiFi built in?


Secondly, did you just follow the exact script on that HA post, assuming you had to modify the dimension calculation to suit your tank?

Tried using the esp32 with home assistant. My head's melted. No joy getting it to work. I'll give it another shot 2m.

Anyone know anything about this:

I'm working on an oil tank sensor using a VL53L0X LIDAR instead of ultrasonic, along with ESPhome and Home Assistant. I'll update on progress if anyone's interested.

oscarBravo wrote: »

So here's what I've got so far:



I have an ESP32 devkit wired to the LIDAR breakout board. ESPhome is running on the ESP32 and reporting reasonably accurate distances. I'm using a calibrate_linear filter to convert metres to litres, but I'm planning to use calibrate_polynomial to hopefully get a somewhat more accurate conversion allowing for the rounded shape of the tank.



I've also 3D printed an enclosure to mount the LIDAR in place of my old Watchman probe. I'll run some outdoor Cat5 cable to the ESP32 which will be mounted on the back of a wee solar panel, along with a solar charge controller/battery module.

I've configured the ESP32 to deep sleep for long intervals, then wake up for a minute, which gives it time to connect to WiFi and update the oil level a couple of times.

Still working on the design for the solar panel/ESP enclosure. When I have it printed I'll report back.

This Magnus monitor seems to do all that is required.
A couple of oil suppliers in Galway and doing a deal on them with your next fill.
Has anyone got one and do they work?

I think i heard it advertised earlier at 9 quid per quarter with free install.
