Homekit-enabled dry switch or 5 v / 12 v switch - How to switch caravan heater ON remotely

Jarmo Hiljanen

Recommended Posts



I have used several hours to find a solution to turn my caravan heater on remotely. The same system setup will enable all other similar controls e.g. switching something ON/OFF native way with Homekit switch. Gates, blinds etc. You name it.


Is it really so, that this is not available? FGS-213, I assume, is not the way to do this. Older switches does the trick, but are not Homekit-enabled.


And yes, I can code this by using Raspberry Pi, but I really do not have time for DIY projects.


Scenario 1

SO, my question is: How to accomplish this:

1. Apple-TV is in the house, connection to Wi-Fi (so I can control the TV and Fibaro devices from my iPhone..)

2. The caravan is connected to 230 V

3. In the caravan I have XX Fibaro device that I assume is not existing now

4. Caravan heater external heating pins are connected to Switch XX

5. The XX is controlled by Apple-TV (or my iPhone) to do ON right now

6. Switch XX's dry switch is turned ON

7. Caravan heater initiates heating sequence 

8. Caravan owner arrives hours later - happy days


Scenario 2

- The setup is similar to Scenario 1, but in this:

1. Switch XX can output 5V or 12 V

2. There is a normal relay board/device connected to Switch XX

3. The caravan heater control wires are connected to relay board

4. The relay board switches the dry switch ON after received control signal from Fibaro XX
