XMPP Actions

This set of actions allows you to send a message to an XMPP user or multi-user chat, or send a message with an attachment to an XMPP user.


  • sendXMPP(String to, String message): Sends a message to an XMPP user
  • sendXMPP(String to, String message, String attachmentUrl): Sends a message with an attachment to an XMPP user
  • chatXMPP(String message): Sends a message to a multi user chat


The XMPP Action service can be configured in services/xmpp.cfg.

usernameThe username of the XMPP account used by openHAB. Most services will require that you use only the localpart of the account's JID. For example if your account's JID is myuser@example.org, then only configure myuser.
passwordThe password of the XMPP account used by openHAB
servernameThe XMPP service to use, e.g. jabber.de. A list of public XMPP services can be found at https://xmpp.net/directory.php
securitymodedisabledNoThe Security mode used for the XMPP connection. Can be either required or disabled. Defaults to disabled, which means that TLS will not be used. Warning: If you change this to non-disabled, then you must make sure that your TLS server certificate can be validated, otherwhise the connection will fail.
tlspinThe TLS Pin used to verify the XMPP service's certificate. Set this in case openHAB's default SSLContext is unable to verify it (e.g. because the XMPP service uses a self-signed certificate). The PIN value is basically the hash of the certificate in hexadecimal notation. Set securitymode to required to enable TLS for XMPP connections. PIN generation is discussed in detail here or see this example. Example: tlspin=CERTSHA256:83:F9:17:1E:06:A3:13:11:88:89:F7:D7:93:02:BD:1B:7A:20:42:EE:0C:FD:02:9A:BF:8D:D0:6F:FA:6C:D9:D3
proxyThe XMPP Proxyserver to use, e.g. gmail.com
port5222The server port to use
consoleusersA comma-separated list of users that are allowed to use the XMPP console
chatroomThe multi user chat to join, e.g. openhab@chat.example.com
chatnicknameopenhab-botNoThe nickname used in the multi-user chat
chatpasswordThe password required to join the multi user chat

Note: openHAB does not resolve SRV entries like other XMPP clients do, you have to setup the server details manually. Generally, if joe@example.org is your XMPP user ID and xmpp.example.net points to the server running the service, set servername to the actual server xmpp.example.net, the user name username to joe and proxy to the domain name part of your user ID example.org.

Example: Google

# You need this "tlspin" if openhab cannot verify the certificate from the google server
# you may need to add the cryptic talk.google.com address of your private google account to the allowed users
# check you openhab.log to found the address after you send something via Hangouts to your openHAB account

Example: Generate PIN

Assuming the PEM-encoded certificate is in a file called jabber.crt (it is PEM encoded if it contains the lines BEGIN CERTIFICATE and END CERTIFICATE with lots of dashes in them) this shell invocation prints the required value for the tlspin= configuration setting:

$ echo "CERTSHA256:$(openssl x509 -in "jabber.crt" -noout -fingerprint -sha256 | sed 's/.*=//')"

You then copy the whole last line into tlspin.
