2 weeks ago Hi there! Thanks for your interest and kind words about the project.
Given your requirements, I think the most practical solution would be a Zigbee-compatible lock that supports remote unlocking, as it’s designed for low power and integrates well with IoT platforms like Home Assistant. Building a similar device from scratch would be quite complex, especially since I don’t specialize in Zigbee, and the protocols involved would require a lot of extra work to optimize for battery power.
Plus, I’m personally not too keen on connecting locks to networks of any kind just a personal preference for simplicity and security!
Hope this helps, and best of luck with your setup! Let me know if you have any more questions.
Hi, This isn't an issue but rather a question / request. First of all, this looks like a great solution! Do you think it might be possible to create a similar device that’s battery-powered, perhaps by using a protocol like Zigbee or Thread instead of Wi-Fi? I have a battery-powered Tuya rim lock, but it doesn’t support remote unlock since the Wi-Fi module mostly stays in sleep mode unless a manual request is made from the lock itself. Here’s the lock I’m using: https://www.ilockey.com/product/tuya-app-waterproof-smart-rim-lock-for-outside-door/
If not, how about adding a small wake-up receiver to a Clicker device? This way, the Clicker would stay in sleep mode until it receives a low-power wake-up signal from a transmitter, like https://seanblanchfield.com/2023/02/esp32-microcontroller-wakeup-receiver or https://www.instructables.com/Remote-controlled-relay/ Once it receives the signal, the Clicker could wake up to activate a device (e.g., the coffee machine in this video).
Instead of using a simple remote key fob to send the wake-up signal, one can use something a combination of a transceiver and MCU that is connected to a power socket or mains. This transmitter could be integrated with IoT platforms like Home Assistant, as a button. When pressed in Home Assistant, the transmitter could send a wake-up signal to the battery-powered Clicker, which would then activate the relay to turn on the device.
The transmitter could also function as a hub, sending signals to multiple Clickers. This way, the transmitter would stay permanently powered, while the battery-operated Clickers could serve as low-power nodes.
