Using the Faradite TAP range with Loxone
The Faradite TAP switch plate range provide a digital output that pluses for the duration of the button press. This pulse acts as an input into the Loxone system and can then be utilised in Loxone config to provide a nearly endless range of functionality, we will look at the range of functions later in this blog.
There are 2 varieties of TAP switches: the TAP-5 and the TAP-1. The TAP-5 provides 5 buttons and the TAP-1 provides a single button. Both TAP switches for Loxone also have an integrated 1-Wire temperature sensor. We will look at how to connect and configure the 1-wire temperature sensor later in the blog.
Wiring the TAP Range
There are multiple ways in which the TAP range of switches can be wired in to the Loxone system, but essentially the TAP range uses 1 digital input per button. Suitable Loxone devices that have 24V digital inputs include the Miniserver, Extension, Dimmer Extension, DI Extension and Nano DI Tree.
To use the inputs on the Miniserver, Extension, Dimmer Extension, DI Extension you must wire in a star topology, and to use the inputs of the Nano DI Tree you must wire in a tree topology. The diagram below shows the difference between a star and tree topology.
Regardless of if you are wiring in a Tree or Star topology we recommend using CAT cable to each TAP switch location to give enough cores for all TAP-5 switch outputs, the 1-Wire temperature sensor and the 24V supply / GND. We do not recommend the use of the “Loxone Tree Cable” because it does not have enough cores to fully support all the functionality of the TAP-5 due to the use of the 1-wire bus for temperature sensors, it is also expensive compared to CAT cable. The diagram below shows the terminations required for the TAP switches.
The TAP-5 is numbered as per the picture below, the TAP-1 only has one output called BUTTON 3 to be consistent with the centre button of the TAP-5.
The temperature sensors included in each TAP switch are 1-Wire sensors and therefore are wired back to the Loxone 1-Wire extension. This requires some careful consideration when wiring as often a single CAT cable will have some cores wired to digital inputs, some wired back to the 1-Wire extension and some cores used for the 24V DC supply to the switch. Accidentally connecting 24V to the 1-Wire sensor will most likely cause irreparable damage to the 1-Wire sensor, so be careful.
Configuring the TAP switches in Loxone Config tool
We start by identifying the digital inputs in the Loxone periphery tree that we have the TAP-5 / TAP-1 switch connected to. Make sure each input is named correctly to avoid any confusion when returning to the config at a later date or if we need to make any amendments. In this example we have wired a TAP-5 back to inputs 4 -8 of the Miniserver. Category and room can be set for each input also.
Here the example shows the Nano DI Tree being used for the TAP-5 inputs and also optional includes the Motion sensor 360 Volt Free input wired back to the 6th input on the Nano DI Tree module:
As we mentioned previously, there are almost endless possibilities with the TAP switches functionality once connected to Loxone. In this blog we are going to give 3 common switch configuration examples and show how these are achieved in Loxone config.
Switch Example 1
To achieve this functionality, we need to take the digital input connected to BUTTON 3 (middle button) and attach it to the lighting controller for the room. As we want this button to provide scene scroll so we attach it to the ‘+’ input on the lighting controller function block. This will also turn off all lights with a double tap of the middle button of the TAP-5.
To achieve the shading functionality, we take the BUTTON 1 digital input and connect it to the rooms ‘Automatic Blinds’ function block 'Cu’ input, we then connect BUTTON 4 to the 'Cd’ input on the same function block.
The right hand side switch buttons are dedicated to music control in the room so we take BUTTON 2 and connect it to the ‘V+’ button on the ‘Music Server zone’ function block as we are using the Loxone Music Server in this example. We then take BUTTON 5 and connect it to the ‘V-’ input on the function block. This will also provide the double tap functions the Music Server Zone function block provides.
Switch Example 2
In this switch example the middle button and the left hand side of the switch (BUTTON 1 and 4) are configured in the same way as in example 1. However, in this example we want to have specific scenes triggered from BUTTONS 2 and 5. To do this we connect BUTTON 2 and BUTTON 5 to the ‘T5/1’ and ‘T5/2’ function block inputs. A tap on these switch areas will now discretely trigger scene 1 and 2 respectively – further presses on this button will continue scene scrolling. In this blog we take a detailed look at integrating the Faradite TAP switch plate range with Loxone.
Switch Example 3
In this example we keep the middle button as the lighting scene scroll functions but each of the 4 outer buttons become control for the Sonos music system. To achieve this we can find the Sonos controls as predefined commands in Loxone config under virtual outputs in the periphery tree. We can then grab these and add them to the Config and connect them directly to BUTTON 1,2,4 & 5.
As we explained earlier in the blog, the TAP-5 and TAP-1 includes a 1-Wire temperature sensor and as such is wired to a 1-Wire extension in the Loxone system. After completing a 1-Wire device search and finding the correct 1-Wire sensors they will appear under the 1-Wire extension in the periphery tree. We can then take the relevant temperature sensor and connect it to the function block that looks after the temperature regulation in the appropriate room.
To make sure users have simple interaction with their smart home we have a custom engraving option which means TAP-5 Switches (Stainless Steel and Brushed Copper) can be beautifully engraved with custom text or icons. This allows users to mark the switch functionality without detracting from the aesthetic of the switch plate.
We would love to see examples of your configurations with the Faradite TAP switches.
