Update BLYNK dashboard when its offline?

The problem is, when there is no device connected to the dashboard it isnt updated. is there a way to use the dashboard when it is offline? Of course I tried to activate an ESP with a dashboard to check if it updates when online and it works, but if I disconnect the ESP the dashboard is offline and cannot be updated.

I’ve read this several times and still don’t understand it. Can you explain more please?

I wanted to create a Python script or whatever is possible to receive data with the MQTT subscribe and transfer it to a virtual pin in BLYNK.

Have you looked at Node-Red?
My home automation systems are built around devices that run MQTT code, and talk to a Pi4 server running Mosquitto. The same server also runs Node-Red and has the Blynk “plug-in” for Node-Red installed.
This allows a seamless always-on integration with Blynk, and whenever a virtual pin changes state it immediately triggers an action in Node-Red.
In the same way, data coming from devices via MQTT into Node-Red can be pushed to Blynk as required.
