Eltako FKS-SV
Battery-free EnOcean actuator
The EnOcean actuator from Eltako is used to efficiently control radiators in private homes and commercial premises. Its great advantage: thanks to thermal energy harvesting between the radiator and the room (rT>4K), it works without batteries or wires, so there is no need for regular battery changes. To ensure proper functioning at all times, it has an additional internal memory. This can be recharged via micro USB if required. The Eltako FKS-SV uses the bidirectional EnOcean protocol EEP-A5-20-01 to communicate with wibutler.
With wibutler the Actuator Part of the demand-led heating and individual room control system. It can be used with all known functions and options:
- Time rules:Perfect temperature control with customised heating schedules
- If/then rules: Energy-saving window open detection
- Night setback: Simple protection against energy wastage
- Voice control: Integration with Amazon Alexa & Google Home
- Remote control: Adjust temperatures anytime & anywhere
It doesn't take much to heat your home more cost-effectively with the EnOcean actuator. Just click on the button below. This will take you to the wibutler shop, where you can order the actuator directly.

Viessmann Vitoair
Central ventilation unit
The Vitoair domestic ventilation system from Viessmann is suitable for ventilating and deaerating residential buildings. For healthy indoor air without compromise, it has an integrated preheater coil in addition to an integrated air filter. The flexible ceiling, wall or floor installation of the appliance is particularly suitable for new builds.
Communication between Vitoair and wibutler takes place via the ViCare account. Once the ventilation unit has been programmed, the familiar functions and benefits of the wibutler energy OS are available:
- Maximum efficiency: Heating (e.g. with a heat pump), cooling and ventilation are optimally harmonised
- Mould protectionSimple networking with external sensors (e.g. humidity sensor)
- Flexible operationOptimum control via presence detection, push-button, remote control, app, voice
- Remote control: Stay in control of the technology from anywhere using your smartphone

Viessmann Vitoplanar
Built-in switch thermostat

The Vitoplanar built-in switch thermostat from Viessmann is used to network your underfloor heating, electric infrared heater, rapid heater or wall vector with wibutler. The thermostat has a floor temperature sensor (3m, extendable up to 50m), a touch display and is mounted on a flush-mounted box using a cover frame. Bidirectional communication with wibutler takes place via a local TCP/IP standard.
It is particularly impressive in combination with electric direct heating systems wherever heat is needed at the touch of a button. For example, in the bathroom, conservatory or hobby cellar. Networking the Vitoplanar built-in switch thermostat and wibutler makes control even easier and heat generation even more energy efficient.
- Self-sufficient livingGenerate and store electricity yourself - and consume it flexibly. Various automation rules control the electric heating in an energy-efficient way.
- Flexible operationEither at the touch of a button, by voice or fully automatically via automation control - with wibutler, electric heating is even easier to control.
- Detailed monitoringThe wibutler app visualises electricity consumption and shows the level of energy self-sufficiency of the house.
Control your electric panel heating or other devices with the switch thermostat. Order it today in the wibutler shop.
