hello all,
I am planning to put my pellet bunker for my heating system on weighing cells so that I can track consumption.
I would connect them as I have often seen them on the net.
How do i connect these cells correctly to the hx711 module?
how do i calibrate the maximum weight? i don't have 2t per cell as a weight in the house. Can you please help me to understand this?

Re: espeasy HX711 with 4x 2T load cell
You already answered that yourself, just follow the wiring schema, and optionally instructions on the internet if needed. I can only assume you already have some experience in soldering electronics, as that seems to be required.
Calibrating is done on the ESPEasy Devices page for the task you add. You will need a 'test' .bin file, as that includes the HX711 plugin.acidsubway wrote: ↑28 Feb 2021, 21:32 how do i calibrate the maximum weight? i don't have 2t per cell as a weight in the house.

You enable the 2 point calibration for both Channel A and B, where you measure it with an empty vessel (point 1), and a fully filled vessel (point 2), of course you will have to know the real weight of the filled vessel to set the right hand side of that comparison.
Instead of a filled vessel, where the weight may be unknown, you can add reference weights close to the (expected) maximum weight.
If the exact amount of fluid in liters/gallons is known, and the weight per liter/gallon too, you can of course multiply those to get the weight.
