Same summary

The Avatto SDL-A270-B -6072 WiFi smart digital lock fits well with the wishes of users looking for a simple yet modern way to control access and increase home security. Due to its WiFi connection, it is suitable for individuals or households that already use or want to enter the smart home ecosystem without the need for additional central units. The lock is less suitable for those looking for full integration into systems with Zigbee or Z-Wave protocols or for very complex automations, as it relies mainly on the WiFi environment. A clear advantage is the user-friendly management via the application and the possibility of quickly upgrading existing entrance doors without major interventions.
