D3IoT is a UK smart energy and property intelligence company that designs, installs and commissions metering across buildings and portfolios.
D3IoT position themselves around investment-grade energy data. For gas, they install MID-compliant gas submeters and AMR that capture half-hourly data and send it to their D3 Cloud platform alongside electricity and water, so heating consumption can be allocated and reported consistently with other utilities.
D3IoT suits owners of multi-let buildings where gas is the least visible utility. D3IoT is also listed under Electric AMRs, for electricity sub-metering and tenant billing.
