Symbiosei IoT sensors for the Home Assistant ecosystem

Indoor microclimate monitoring, garden sensors, liquid level measurement, soil temperature and moisture

All our devices are designed by practicing engineers to work in real, harsh conditions. Our standard is native integration with Home Assistant, open architecture, and operation in a local loop without external cloud serve rs.

Delivery Format: Easy-DIY Kit

We supply devices in the Easy-DIY Kit format (fully soldered, tested circuit board + casing elements for final assembly). This allows you to:

  • Optimize customs duties when importing.
  • Legally involve local personnel for final assembly, meeting KPIs for job creation.
  • Get maximum flexibility in design (boards can be integrated into our signature biodegradable material casings or adapt casings to your architectural concept).

The final device cost is not a public offer: it is calculated individually and depends on the batch volume, logistics, and your readiness for self-assembly.
For large infrastructure orders, targeted regional certification may be conducted and exclusive distribution rights provided.

Protective and decorative casings

If needed, we are ready to develop protective and decorative casings adapted to the specific features of your project (from biodegradable polymers and bamboo to architectural ceramics).

1. Climate monitoring sensor for indoor spaces

Our flagship development for predictive control of air and thermal environment in residential and infrastructure zones.

The layout of the components is designed so that the operation of the display does not affect the thermometer readings and does not disrupt air circulation

  • Open housing architecture: The design provides direct contact of the measuring elements with the air environment. The result is an increased response speed of the sensors to changes in humidity, CO₂ levels, and temperature.
  • Integrated display without thermal interference: The board comes with a pre-soldered screen for local data display. The layout of the elements is designed in such a way that the display operation does not affect the thermometer readings and does not disrupt air circulation. This ensures high measurement accuracy with convenient visual control of parameters right at the device's location.
  • Economy: In Easy-DIY Kit format, the solution remains fully accessible for mass equipping of large civil and commercial facilities.

2. Ultra-budget water level sensor (African case)

An engineering solution with extremely low cost, designed for humanitarian, infrastructure, and agricultural projects in developing regions where price affordability is critically important.

  • Feature: The principle of utilitarian sufficiency and maximum simplification of peripherals. The board is designed so that the end user can use a regular plastic bottle as a reliable protective case on site. The solution is resistant to local climatic conditions and easily maintained by local specialists.
  • Economy: When ordering medium-sized batches (from 100 units), the cost of one board drops to an unprecedented $3-5.
    This is an effective tool for scaling up monitoring networks (for example, monitoring tank or sewage overflow) under conditions of strict budget constraints.

3. Autonomous Soil Moisture Sensor (For Remote Areas)

A specialized solution for landscape objects, large-scale eco-gardens, and remote agricultural complexes where there is no stable communication infrastructure and power supply.

  • Communication Range: An optimized radio contour ensures stable data transmission up to 2 km in line of sight. Depending on the location and project requirements, the device is equipped with either a Wi-Fi module or a radio transmitter operating on standard civilian frequencies.
  • Extreme Power Supply: The power management unit allows the sensor to operate reliably for over a year on a single charge in a harsh temperature range from -10°C to +40°C.

4. Garden probe with external sensors (Deep monitoring)

A professional tool for landscape architects working with complex terrain, ancient trees, and demanding ecosystems.

  • Feature: Modular architecture with external measuring elements.
  • Result: Allows continuous layer-by-layer monitoring of soil moisture and temperature to a depth of up to 1.5 meters. An indispensable element for predictive management of automatic irrigation, preventing root rot of valuable tree species and saving up to 40% of water during watering.
An affordable, reliable, and small-batch-ready garden sensor with external sensors: soil temperature and moisture at depths of up to 1.5 meters, air temperature and humidity, and light level
