Thank you for your feedback. The delay you’re experiencing with the Z-Wave switch can vary due to several factors. Wireless sensors rely on communication protocols that can be influenced by network traffic, signal interference, or even the number of hops (or relays) required for the signal to reach the switch. While a typical delay of around 1 second is expected, the 4-6 second delay may indicate temporary congestion or interference in the Z-Wave network.
Additionally, we do apply filtering to RF wireless sensors, particularly those operating at 319 MHz. Depending on how many devices are communicating via the 319 MHz or 900 MHz receivers, and how many receivers are in use, this filtering could be contributing to the delay. The system processes signals in the order they are received, and if multiple devices are transmitting simultaneously, it may cause the delay to vary.
We will conduct some testing to see if we can further minimize these delays and improve overall consistency. As you stated for situations like turning off lights, the slight delay is generally more acceptable, but we understand the importance of quicker responses for turning lights or other automations on.
