+====== 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.

 The device registers itself on the Zigbee network with manufacturer and model identifiers, sets reporting intervals and tolerances for each sensor type, and reacts to identify commands by blinking its LED. If Zigbee fails to initialize or connect, it restarts the ESP32.

 In this next example we will simulate a Zigbee smart lightbulb controlled by a Zigbee light switch, using two ESP32-C6 Sparrow nodes.

+====== 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.
