Looking for a continuous measurement scale

Hi, I am looking for a continuous measurement scale I can integrate in HA or better already integrated. To clarify the need, I put a plant on the scale and trigger when the weight has decreased some amount after watering, for new watering (I use also in addition a soil humidity sensor). Required precision 10g and range 1kg preferably 10kg.

So domestic scales which power on when you stand on it and then put itself on standby do not fit my needs and the precisions are usually too bad (50g to 100g).

Then there are lab or medical scales which have RS232 to request the weight. But I have found none which claim HA integration, and I would prefer bluetooth or zigbee communication.

Is there some scale fullfilling my needs please, I have spent hours unsuccessfully at this time ?

There are a number of DIY projects for ESPHome that use load cells to measure things like propane cylinder capacity.
