Hey everyone! I wanted to share a project I’ve been working on for the past few months—a DIY ESP32 security panel. The goal was to create a reliable and customizable system that integrates with my smart home setup. Here’s what I came up with!
The Build
The panel combines several modules to deliver robust functionality:
- Wireless-Tag WT32-ETH01 Ethernet Module: For a more secure and low-latency connection compared to Wi-Fi.
- MCP23017 IO Expansion Module: Adds 19 GPIO channels for flexibility.
- Generic 4-Channel Relay: Controls various devices around the house.
- 3.3V/5V Power Supply Module: Ensures stable power delivery.
- Terminal Connectors: For easy wiring and expansion.
The end result is a compact, feature-rich security panel with 4-channel relay, 19-channel GPIO, Bluetooth, Wi-Fi, Ethernet, and screw terminals. It’s been a fantastic learning experience, and I’m proud of how it turned out!
Integration with Govee Remote Control
Another project I’ve been exploring is integrating Govee smart lights with a physical remote control. I’ve installed several Govee M1 strips, but their control interface is a bit inconvenient for my workspace setup. I’ve been searching for a sleek, wireless remote that can toggle multiple devices simultaneously. Unfortunately, Govee doesn’t offer such a product yet, but I’ve found some workarounds using their app and smart home integrations.
Automation Tips
For those interested in home automation, I’ve been experimenting with custom sun sensors. Sometimes, the elevation that works for sunset isn’t perfect for sunrise. Here’s a quick template I’ve been using to adjust the sensor logic dynamically:
yaml
sensor:
platform: template
sensors:
my_sun:
entity_id: sun.sun
value_template: >
{% if is_state_attr(‘sun.sun’, ‘rising’, True) and state_attr(‘sun.sun’, ‘elevation’)|float > -4.4 %}
above_horizon
{% elif is_state_attr(‘sun.sun’, ‘rising’, False) and state_attr(‘sun.sun’, ‘elevation’)|float > -1.5 %}
above_horizon
{% else %}
below_horizon
{% endif %}
This allows for more precise sun tracking and automation triggers.
