garden watering valves and soil sensors

[DarioKTS]

Hey all, new memeber of the forum here :).

I've recently re-organised my home's lighting using zigbee2mqtt within a docker container, works flawlessly.
Now i'm onto the garden. i've noticed there aren't many soil sensors and watering valves in the device database.
I've been looking at these 2 :
sensor
valve

I'm more than willing to go through the process described in the "support new devices" section, and contribute to the device database, would just like to know if there is any chance that a device might outright not be compatible, so that i can switch to some other model before purchasing some unwanted paperweight..

thanks in advance

Hi,

At home we've got the same sensors, and made a start on getting things working. We don't have a Tuya hub, so are just getting the datapoints that it reports to a Zigbee receiver.

This is as far as we got, by having a best-guess at the meaning of the datapoints, which might help as a head start:

• Datapoint 3 - We guess this is the moisture, we've seen it drop to zero when removing the sensor from the soil
• Datapoint 5 - Appears to be temperature in °C
• Datapoint 14 - A status-byte? When it reports '1' the other values appear valid.
• Datapoint 15 - Maybe the battery percentage?

const tz = require('zigbee-herdsman-converters/converters/toZigbee');
const exposes = require('zigbee-herdsman-converters/lib/exposes');
const tuya = require("zigbee-herdsman-converters/lib/tuya");
const utils = require("zigbee-herdsman-converters/lib/utils");
const reporting = require('zigbee-herdsman-converters/lib/reporting');
const extend = require('zigbee-herdsman-converters/lib/extend');
const e = exposes.presets;
const ea = exposes.access;


const definition =
