• Sometimes the error code "210003" was displayed when the Stromer was switched on because the battery or the power supply was switched on with a delay. New, the error is cleared when the power supply was successfully switched on.
• If an overvoltage is detected, then the recuperation is deactivated.

Charger

• Sometimes, after removing the charger, the error code "210110" was displayed on the Stromer because the power supply was not below a specified threshold during the functionality check after 1 second. Now the error is only displayed after 4 seconds.
• If the type of the connected charger cannot be identified, the type of the previously connected charger no longer applies. This prevents the wrong firmware from being downloaded for the charger.

Various optimizations

• Now, the sensor value is monitored and tracked to ensure consistent support.
• It is now detected whether pedaling is taking place during the ride. 
• If the PIN code is forgotten/lost on a Stromer with OMNI Interface C, the code can be reset by the specialist dealer after presentation of a vehicle ID or proof of purchase.

• For batteries with firmware version "1.57", "2.57", "3.57", "4.56", "5.3" or "6.3", the safety functions have been optimized.
• Driving clearance is withdrawn if it is determined that the battery cannot be deactivated.

Connectivity

• For Stromer ST1 (2019 or newer), which are equipped with an OMNI Interface C, the "SmartLock" function has been enabled.
• The sensitivity range of the SmartLock function has been extended. This allows the range in which the Stromer is unlocked/locked when the paired device is in the vicinity to be set more precisely.

Various optimizations

• The support dynamics of the individual support levels 1 to 3 were distributed more evenly.
  - Mode 1 is still very economical and corresponds to an ECO mode.
  - Mode 2 has been optimized (default setting) so that the assistance level is positioned midway between modes 1 & 3. The mode can be adjusted to personal needs via the Stromer OMNI app.
  - Mode 3 now provides slightly stronger support while maintaining the same sensor sensitivity.
• Optimizations were made to the sensor dynamics for Stromer ST5 & ST3. These adjustments have reduced the amount of force needed until the motor assistance kicks in.
• A QR code can now be displayed in Menu/Bike/OMNI (only with OMNI Interface C). This will make it possible in the future to link the Stromer with the account without having to visit the dealer (an update of the app is necessary, which will be released soon).
