Get Sdcard/Hdd existance and size used

Hi @StarKillerOG, i have a other idea to offer the information of the status of the SdCard or Hdd if exists and, if the case, his size used. Through the command GetHddInfo, you get have the status and size used:

Here GetHddInfo returns ;
```
jeedom@jeedom:~/rl-api $ ./rl-api22.sh GetHddInfo '{"channel":0}'
{
"HddInfo": []
}
```
In that case, it's a good information for HA to know if there is no storage These is no SdCard or Hdd in the camera

If it's a case that storage exists, here how to check the size used

here GetHddInfo returns :

jeedom@jeedom:~/rl-api $ ./rl-api29.sh GetHddInfo '{"channel":0}'
{
"HddInfo": [
{
  "capacity": 30462,
  "format": 1,
  "mount": 1,
  "number": 0,
  "size": 779,
  "storageType": 2
}
]
}

In that case, if the field 'StorageType' is equal at 1 it's a a Hdd and 2 if it is a SdCard

To have the size used of the device, here the command : round(size*100/capacity) In that example : round(779x100)/30462 -> 3%
