# Synopsis

Thng Properties that were created with the `evrythng-extended.js` SDK and ARE NOT
URL encoded are not being published by the MQTT broker at mqtt.evrythng.com

# Description

In my custom Reactor script, I was creating Thng Properties that look like the following:

```
__rule__efb705593acd44cbb828e4e52befdf30__condition__ambient_light_>_5_@10s
```

Note the `>` and `@` symbols. I was creating these Properties using the
`evrythng-extended.js` SDK with the following command:

```javascript
app.thng(this.thng.id).property($PROPERTY).update(payload).then((response) => {
  "..."
})
```

...where `$PROPERTY` was a string like the above example.

When I subscribed to the MQTT topic of the Thng that the above Property was on,
I recieved updates to every Property EXCEPT that one. When I changed the name
to the following:

```
__rule__efb705593acd44cbb828e4e52befdf30__condition__ambient_light_LT_5_10s
```

I recieved those Properties just fine.

I tested this out using MqttFx, to be sure it was an issue on your end, and got
the same result.
