I have dowloaded data from my Ewelink Thermostat (TRVZB), where the state of the thermostat stored in "thermostat-mode" object. Im unable to get or transfer this data to my global variable, because the hyphen in the name not accepted.  
Any solution?

1. Use a change node instead of a function node.
2. Use square bracket notation instead of dot notation.

You can either quote it or place in between square brackets. For example:

```auto
obj = {
   "thermostat-mode": xyz
}

```

or

```auto
mode = obj["thermostat-mode"]

```

Thanks!  
In the meantime I found the answer in "Use an object with a hyphen in a function" topic. Same like OMRID advice.

Thanks again your time and quick answer.

(You should make the thread as `solved` to show it has been answered.)
