IoT monitoring and automation platform for building heating systems

Utilities Alzenau, Bayern 11–50 employees Founded 2018 Public Company

othermo builds remote monitoring and optimization software for district heating, gas heating, and heat pump installations across Europe. The tech stack reveals an engineering-first organization: PostgreSQL + TimescaleDB for time-series data, MQTT/BACnet/Modbus for industrial IoT protocols, Python/FastAPI for the API layer, and Prometheus/Grafana for observability—a mature architecture for handling continuous sensor streams at scale. Active hiring leans heavily toward mid- and senior-level engineers (7 of 9 open roles), suggesting both product velocity and the technical depth required to manage OTA updates and cross-vendor device integrations.
