To query a remote system at least the address (HOST) must be specified. Accompanied by the port and / or user name, if necessary. The password (if needed) has to be defined once with the command 'set password &lt;password&gt;'. For MODE parameter are 'telnet', 'ssh' and 'local' only allowed. 'local' does not require any other parameters and can also be omitted.
<br>
For SSH login with password, 'sshpass' must be installed (note: not recommended! Use public key authentication instead).
For SSH login to work, a manual SSH connection to the remote machine from the FHEM-Acount may need to be done once
(under whose rights FHEM runs) the fingerprint must be confirmed.

Das eventuell ben&ouml;tigte Passwort muss einmalig mit dem Befehl 'set password &lt;pass&gt;' definiert werden.
Als MODE sind derzeit 'telnet', 'ssh' und 'local' erlaubt. 'local' erfordert keine weiteren Angaben und kann auch ganz weggelassen werden.
<br>
Bei SSH-Anmeldung mit Passwort muss 'sshpass' installiert sein (Achtung! Sicherheitstechnisch nicht empfehlenswert! Besser Public-Key-Verfahren benutzen).
Damit SSH-Anmeldung funktioniert, muss ggf. einmalig eine manuelle SSH-Verbindung an die Remote-Machine von dem FHEM-Acount
(unter dessen Rechten FHEM läuft) durchgef&uuml;hrt und fingerprint best&auml;tigt werden.
