Hello all,
I’m running an integration since a couple of year, and collected a lot of statistics that I want to keep.
Over time this integration, not for the integration per se, loose connectivity with the device queried for the data ( the proble is the device ) so I decided to create my own device, based on ESP8266 to get the same data in a different way.
At the moment my device is returning data via MQTT while the original integration was using a different ( Modbus over TCP ) method.
Now the firmware I wrote is almost complete, so I would like to swap the way I get the values from the old integration to this new one method ( obtained by MQTT ).
What’s the best way to achieve this while not loosing historical data ?
I’m not sure I’ve been able to explain my need, but I hope so
Thanks in advance.
Pierluigi
