Requirements and interfaces
The interface must be present, enabled and authorised for the required write functions on your installation. Some devices need an additional gateway. Meter readings or simple surplus-switching signals alone do not provide comprehensive heating control.
EMS-ESP schedules and temperature controls depend on the controller and firmware. The project lists CT200/TC100 as read-only. A readable return temperature does not establish a writable return setpoint; Lambda’s corresponding requests depend on the buffer configuration.
We plan additional gateways and individual adjustments for your installation. Device and comfort limits remain binding.
Interface sources, as of 12 October 2026: EMS-ESP, EMS-ESP-controllers, Lambda, NIBE, STIEBEL ELTRON, Daikin.
Depending on the EV charger or heat pump, EVCC functions may require a sponsor token. Read about tokens and external costs.
More than a standard list
We review pools, irrigation and special systems individually.
Even if your device is not listed, secure integration may be possible through an existing or manufacturer-approved interface. RKV assesses not only whether data can be received, but also which automation, controls and protective logic make sense for your use case.
