+====== Lab 5. Zigbee Networking ======
 Zigbee is a low‑power, low‑data‑rate wireless protocol for building sensor/actuator networks (home automation, smart energy, lighting, industrial monitoring). It sits on top of IEEE 802.15.4 radios and adds networking, security, and application profiles.

+====== Switch as a Sleepy ED ======
+The previous example has the downside that the ED can be battery powered, but the code is not particularly optimized for energy saving. As a regular user will not press the switch more that a dozen times a day, it makes a lot of sense to keep the switch ED in deep sleep and wake only when the button is pressed. waking from deep sleep equates to having a hardware reset, so we will need to persist switch logic into the non-volatile RTC memory. This is all handled in the code below.
+[[iothings:laboratoare:2025_code:lab5_3|Click here to get the code for this example.]]
+<note>**Assignment 1:**
+Use the on-board BME680 sensor to switch lights on/off depending on the switch temperature instead of pushing a button. For example, if the temperature is above 25 degrees C, the light should turn on.
+</note>
+<note>**Assignment 2:**
+Encode more than simple on/off behavior from the switch. For example, a press toggles, and a hold dims up/down. Add a long-press detector on GPIO 9 and send MoveWithOnOff / Stop commands; on the bulb, implement Level Control callbacks to set NeoPixel brightness with transition times.
