If you are okay with duplicating (caching) data, you can cache them locally (on your central gateways) using a couple of options:
- Cache values locally using GAN. Create a local tag provider which contains folders of reference tags to remote tag providers. The values will update based on the tag group of the reference tags.
- Cache values using MQTT. Convert your Edge providers from GAN to MQTT. Values will be sent to local gateway(s) as values change, thereby caching the remote tags on your local gateway.
In both cases, your local script will be updated to read from (and write to) the reference tags on your central gateway.
