About Tendry Lab
Environmental monitoring systems that you completely own and control.
Tendry Lab builds environmental monitoring systems that you completely own and control. From hardware to firmware to data infrastructure - everything runs locally, nothing requires cloud services, and your data never leaves your network.
We see a future where environmental monitoring becomes as common as checking the weather. As people increasingly track how they use resources - water, energy, air quality - the volume of data about our most private spaces will grow exponentially. This data reveals patterns of daily life, resource usage, and personal habits. It should never be required to share it with third parties.
That's why we build local-first systems. Your environment, your data, your infrastructure. We provide the complete stack - production hardware, stable firmware, web interfaces, and data tools - but you host it, you control it, you decide what to do with it.
Everything we build is open source. The platform that powers our products is available for anyone to use. If you want to build your own environmental monitoring product, you can use our firmware, UI components, and data infrastructure. We're building tools for a future where people monitor and optimize their resource usage without surrendering their privacy.
We're currently shipping bonsai, our first product for soil moisture monitoring. The same stack that powers bonsai is available for developers to build their own monitoring systems.
