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

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
