CloudMQTT Alternatives

CloudMQTT is shutting down services on 1/1/2025 and I currently use CloudMQTT in conjunction with OwnTracks in conjunction with an internal facing instance of Home Assistant. I do not have any plans to expose my instance of HA to the internet.

Do you have any suggestions for alternative solutions to handle location based automations? Its also fair to note that I only use MQTT for location.

Thank you!
