Different Type In GetDeviceTriggerCard
Introduction
When working with the DeviceTriggerCard in Homey, it's essential to understand the different types of arguments that can be passed to it. In this article, we'll explore the various types of arguments that can be used with the getDeviceTriggerCard, specifically focusing on the arg type. We'll examine a code snippet that demonstrates the issue with the arg type in standard and advanced flow types.
The Issue with arg Type
The code snippet provided shows a registration of an argument autocomplete listener for the button argument. The listener is designed to retrieve a list of services from a device and filter them based on their type. However, when accessing the aid property of the args.button object, the type is Number in standard flow, but String in advanced flow.
### Code Snippet
```javascript
this.homey.flow.getDeviceTriggerCard('multy_button_clicks')
.registerArgumentAutocompleteListener('button', async (query, args) => {
const device = args.device as SprutHubDevice;
const data = device.getData()
const services = await (device.driver as SprutHubDriver).getServices(data.aid);
const filter = services?.filter(service => service.type === 'StatelessProgrammableSwitch')
for (const value of filter || []) {
console.log('*** aid', value.aId, typeof value.aId);
console.log('*** sid', value.sId, typeof value.sId);
}
return filter?.map(service => ({
name: service.name,
aid: Number(service.aId),
sid: Number(service.sId)
})) || [];;
})
.registerArgumentAutocompleteListener('click_type', async (query, args) => {
if (!(args.button)) {
return [];
}
const device = args.device as SprutHubDevice;
const data = device.getData()
// console.log('*** data', data);
console.log('*** aid', args.button.aid, typeof args.button.aid); // Number in standart flow, but string in advanced
console.log('*** sid', args.button.sid, typeof args.button.sid);
const service = await (device.driver as SprutHubDriver).getService(args.button.aid, args.button.sid, true);
return service.characteristics?.flatMap(characteristic => {
if (getCharacteristicControl(characteristic).type === 'ProgrammableSwitchEvent') {
const val = getCharacteristicControl(characteristic).validValues
?.filter(value => value.checked === true)
?.map(filteredValue => ({
name: filteredValue.name,
value: filteredValue,
aId: characteristic.aId,
sId: characteristic.sId,
cId: characteristic.cId
})) || [];
console.log(val);
return val
}
return [];
}) || [];
})
.registerRunListener(async (args, state) => {
if (state.aId === args.click_type.aId && state.sId === args.click_type.sId && state.cId === args.click_type.cId) {
return Object.values(state.control.value)[0] === Object.values(args.click_type.value.value)[0];
}
return false;
});
Understanding the Issue
The issue arises from the fact that the arg type is not consistent across different flow types. In standard flow, the aid property of the args.button object is of type Number, while in advanced flow, it is of type String. This inconsistency can lead to errors and unexpected behavior in the code.
Resolving the Issue
To resolve this issue, we need to ensure that the arg type is consistent across different flow types. One way to achieve this is by using the Number function to convert the aid property to a number, regardless of its original type.
### Code Snippet
```javascript
const aid = Number(args.button.aid);
const sid = Number(args.button.sid);
By using the Number function, we can ensure that the aid and sid properties are always of type Number, regardless of their original type. This will resolve the issue and ensure that the code behaves consistently across different flow types.
Conclusion
In conclusion, the issue with the arg type in the getDeviceTriggerCard is a common problem that can arise when working with different flow types. By understanding the issue and using the Number function to convert the aid property to a number, we can resolve the issue and ensure that the code behaves consistently across different flow types.
Best Practices
To avoid this issue in the future, it's essential to follow best practices when working with different flow types. Here are some best practices to keep in mind:
- Use consistent data types: Ensure that the data types used in your code are consistent across different flow types.
- Use type conversions: Use type conversions, such as the
Numberfunction, to convert data types to a consistent type. - Test thoroughly: Test your code thoroughly to ensure that it behaves consistently across different flow types.
Introduction
In our previous article, we explored the issue with the arg type in the getDeviceTriggerCard. We discussed how the aid property of the args.button object is of type Number in standard flow, but String in advanced flow. We also provided a solution to resolve this issue by using the Number function to convert the aid property to a number.
In this article, we'll answer some frequently asked questions (FAQs) related to the getDeviceTriggerCard and the issue with the arg type.
Q: What is the getDeviceTriggerCard?
