Firmware Update

Perform firmware update

1. Select the device for updating: “Update” or “Update Communication”

• Update: Firmware of the device

• Update Communication: Update the communication module

Note: To perform several updates in parallel, you can open several links in a new tab by right-clicking on the link.

2. Select “Update firmware”

Duration until start: 

• With Telstar (CT) and Pico, it can take up to 5 minutes.

• For M-Bus Gateway it depends on the upload interval.

3. Wait until the update is complete and confirm with “OK”

Note: If the update has started (> 1%), the browser does not need to remain open.

Duration until the update is complete: 

• For Telstar (CT) approx. 5 minutes.

• For Pico it can take up to a day. See below for how to speed up the firmware update.

• For M-Bus Gateway it depends on the upload interval.

Speed up firmware update

As a general rule, the update continues even without active monitoring or an open browser.

If the update is actively monitored, it can be speeded up as follows:

• Select the meter or pico in a second tab in the browser.

• Select the normal view.

• Leave the tab open and active in the browser. As a result, the meter or Pico communicates more frequently with the smart-me Cloud and more data packages can be exchanged to complete the update more quickly.

• Whether communication is active can be determined by the voltage. As this always fluctuates slightly, it is easy to see whether the device is now sending data every 1-2 seconds.
