A tool to facilitate the digital monitoring of cookstoves in line with the approved methodology for Technologies and Practices to Displace Decentralised Thermal Energy Consumption (TPDDTEC) which involves replacing baseline cookstoves with either (a) more energy efficient and/ or (b) cleaner fuel alternatives. The tool covers digital components such as sensors to monitor stove usage intensity and digital scales which log the mass of fuel (for fuel consumption) during Kitchen Performance Tests (KPT).
