In building retrofits, LoRaWAN competes with EnOcean for energy sub-metering and wireless monitoring (temperature, CO2, presence): long range (one gateway covers a large building), 5-10 years of battery life on the sensors, but higher latency (Class A).

LoRaWAN typically reaches 500 m to 1 km indoors (so a single gateway can cover an entire large building), with a latency that effectively equals the uplink period — usually minutes for a Class A device. EnOcean only reaches 30-50 m indoors and therefore needs many gateways, but it offers second-level latency for instantaneous control. LoRaWAN is therefore preferred for monitoring use cases: retrofit sub-metering (10-100 meters per gateway), tertiary-sector monitoring for regulatory reporting (in France, the OPERAT platform under the Décret Tertiaire) and warehouse or factory logistics. EnOcean remains the better choice for instantaneous control (push-buttons, lighting commands).

When a building owner needs both monitoring and lighting control, propose a hybrid stack — LoRaWAN for slow monitoring data, EnOcean or DALI for the live control — rather than forcing one technology to do both jobs.
