LTS14 On-Premises Connector Host

We are excited to announce the release of LTS14, the latest long-term support version of the On-Premises Connector Host.

With this release, the Connector Host now supports:

• Specifying a base path for an HTTP connector environment
• Writing to OPC UA and MQTT natively in Tulip
• Allow users to define a default value for OAuth token refresh
• A new setting to expose the clean session field when creating an MQTT connection
• Various bug fixes and feature improvements

Write to Machine Attributes

You can now write back to your machine attributes with OPC-UA and MQTT data sources without requiring additional middleware through Tulip.

For more details, see the knowledge base article:
Write to Machine Attributes Using OPC-UA & MQTT

Allow users to define a default value for OAuth token refresh

The "Expires In (s)" field in the Connector environment configuration settings for OAuth2 integrations now supports default values. This setting provides a fallback expiration time if the expires_in property is missing from the response and a refresh_token is available.

Configure MQTT Connectors to Start Sessions with clean = false

A new configuration field has been added when creating an MQTT connection. This field determines whether the broker should store messages while the Connector Host is disconnected. Learn more about this [here] .(https://support.tulip.co/r230/docs/how-to-build-your-first-mqtt-data-source)

Check if Your On-Prem Connector Host (OPCH) Needs an Upgrade

Starting with LTS14/r308, Tulip will enforce version alignment between the **Tulip Cloud and On-Prem Connector Host (OPCH) to ensure feature compatibility. Learn more here.

If your OPCH requires an update, you can check this in the Account Settings page when a supported OPCH version is available. The information will include:

• How to upgrade
• Which OPCH version to upgrade to
• When the upgrade needs to be completed
