Zigbee2mqtt types

This is an auto generated lib containing concrete types that can easily serialise/deserialiwe any json MQTT payloads from zigbee2mqtt.

How to use

To speed up compile time all structs are behind feature flags, these are split into vendors e.g. if you are using a sensor by xiaomi then you will need to add the xiaomi feature to your Cargo.toml like zigbee2mqtt-types = {features = ["xiaomi"]}

Example of using a door contact sensor debug is also a feature so for this to compile the following Cargo.toml line is needed zigbee2mqtt-types = {features = ["debug", "xiaomi"]}

use zigbee2mqtt_types::vendors::xiaomi::ZigbeeMccgq11lm;

#[test]
fn contact_sensor_mccgq11lm() {
    //https://www.zigbee2mqtt.io/devices/MCCGQ11LM.html
    let json = "".to_owned() +
        "{\n" +
        "    \"voltage\": 2995,\n" +
        "    \"battery\": 97,\n" +
        "    \"device_temperature\": 19,\n" +
        "    \"power_outage_count\": 6,\n" +
        "    \"linkquality\": 247,\n" +
        "    \"contact\": false,\n" +
        "}";
    let parsed: ZigbeeMccgq11lm = match serde_json::from_str(&json) {
        Ok(contact) => contact,
        Err(err) => {
            println!("{:?}", err);
            assert!(false);
            unimplemented!()
        }
    };

    assert_eq!(2995, parsed.voltage);
    assert_eq!(97, parsed.battery);
    assert_eq!(19, parsed.device_temperature);
    assert_eq!(6, parsed.power_outage_count);
    assert_eq!(247, parsed.linkquality);
    assert_eq!(false, parsed.contact);
}

Last gotcha is all not all model/vendor names strings conform to Rusts struct/package naming convention, so I needed todo some transformation to them. Models roughtly remove all invalid chars and have Zigbee infront of them. Vendors have an _ in place of any invalid chars example of changes to models

"ZS057-D0Z" = "ZigbeeZs057Dd0z"
"BF 265" = "ZigbeeBf265"
"5110.40" = "Zigbee5110F40"
"MEAZON_BIZY_PLUG" = "ZigbeeMeazonUbizyUplug"

example of changes to vendors

"Eaton/Halo LED" = "eaton_halo_led"
"Custom devices (DiY)" = "custom_devices__diy_"
"Villeroy & Boch" = "villeroy___boch"
"J.XUAN" = "j_xuan"
 // the bellow is just removing non ascii chars I would personally prefer to swap them for similar ascii but for now I will _
"Müller Licht" = "m_ller_licht"
"Sinopé" = "sinop_"

Model function that does conversion is here Vendor function that does conversion is here

Why

While creating a recent project I found myself being lazy with how I was defining my structs to consume MQTT payloads and given they are already defined in Zigbee2MQTT I went looking for a way to generate them programmatically.

Contributions

All development should be in the generator binary as zigbee-herdsman updates too frequently to maintain human updating of this lib.

Future goals

• improve lib documentation
• some sort of type extension to allow last seen to be correctly parsed
• add get set methods
