How to make a persistent virtual device in the Smart Home sample? - actions-on-google

Question

I just downloaded and ran the sample from here. It is working but whenever I connect to the web site (https://something.ngrok.io/) or even refreshing it takes a lot of time andd the Node.js console shows it is getting a lot of "/bower_components", also even thought I have log in with the same account ("rick/oldman"), previously-added devices are gone.
I want to add a persistent simple virtual light, so I saw datastore.js, and either the documentation is missing or I could not find it. The only thing I could find was the comment.
/**
* Structure of Data
* {
* <uid>: {
* <device id>: {
* properties: {
* <property name>: <property value>,
* <property name>: <property value>
* },
* states: {
* <state name>: <state value>,
* <state name>: <state value>
* }
* },
* <device id>: {...}
* },
* <uid>: {
* <device id>: {...},
* <device id>: {...},
* <device id>: {...}
* },
* ...
* }
*/
There was no sample, so I inferred from the logs (created a device on the web site), and created one like this, but this device does not show up.
const config = require('./config-provider');
const Data = {
"f9b2dc04-2518-11e8-b467-0ed5f89f718b":{
"light1":{
"states":{
"on": false,
"online":true
},
"properties":{
"type":"action.devices.types.LIGHT",
"traits":["action.devices.traits.OnOff"],
"attributes":{
"temperatureMinK":2000,
"temperatureMaxK":6500
},
"name":{
"defaultNames":[
"Fake Light"
],
"name":"Fake Light 1",
"nicknames":[
"fake lamp"
]
},
"willReportState":false,
"roomHint":"",
"deviceInfo":{
"manufacturer":"Fake Home Provider",
"model":"fake1234",
"swVersion":"1.0.0",
"hwVersion":"1.0"
},
"customData":{
"smartHomeProviderId":"thisisfakesuperfake"
}
}
}
}
};
I am not sure if the data is correct or not; I could not find any sample for that. What do I need to do to have a persistent virtual device and prevent re-downloading the bower components?

Answer 1

This behavior was introduced to make it easier for testing different configurations. The behavior happens here in the sample code:
app.post('/smart-home-api/reset-devices', function (request, response)
This behavior may be a bit weird depending on how people use the sample, so I have added a new configuration option: Config.enableReset.
By default, it will be true. However, by setting that to false it should persist the devices across page refreshes.
As for Bower, it should not be downloading the files every time, I think those logs are just noting that the files are being "Gotten" from the server. I believe the server caches the responses, so you may be seeing status codes in the 300 range instead of 200.
