Hello, I am a long time Smartthings users. I am now running my home in a mix of Smartthings and other hubs.
I am also a maker. I made Zigbee Environment Sensor which have been used by many member here.
I am now making a couple new devices that take advantage alternative energy. The goal is to minimize our dependency on battery. In my personal experience, once I have a lot of battery powered devices the effort of maintaining them is mentally exhausting. Because of this, I turn to my hobby and take small steps to make devices that uses Energy harvesting as its power.
Don’t get me wrong. The devices that I am making is still using battery due to power requirement in certain state. However, with energy harvesting, I am aiming to have battery life that is in order somewhere 10+ years versus typical 6 to 24 month battery life for Zigbee devices.
In one case, I am able to replace the power by energy harvesting. The battery is needed for a backup only. Here is the first device that I make. It is an Fireplace smart controller.
Another device that I make is a gas stove sensor. This is an example where the battery is the primary source. As the sensor detect the use of the gas stove, It is also harvest the energy. It is a little bit different strategy of taking advantage the harvested energy from the fireplace controller. The energy harvested can be used to add more functionality.
I apologize if you notice that in some of the short video that you are not seeing our beloved hub. During the development, I tested the devices with Smartthings hub. I do not want to trigger “hub versus hub” discussion. I want to mentioned that the devices are Zigbee 3.0 compatibles which allow the device to work with many HA hubs.
At this point, I just want to introduce them to the community. Some may have said that I have been mostly missing from ST community. I am now back. I plan to make it available to the community member in the future like my Environment Sensor.
At last, I would like to take this time to thank everyone here for their support on my Environment Sensor project. Especially, I would love to thank everyone who purchases them. The proceed allow me to make new devices like these new devices. It has been fun learning experience for me. I hope using the energy harvesting for our devices would help all of us to take the first leap in making the next generation devices.
