Loxone Kit: Part 2

November 10, 2014 /

This blog entry covers the Loxone kit that has been installed in the newer part of the property.  You will find a separate blog entry here for the Loxone kit in the older part of the house.

The main distribution board for the property is on the left.  The electricity meter is just on the other side of this wall.  The three distribution boxes house the Loxone kit.  These are the same Hagar units that we used in the other part of the house.

The top distribution board has a Loxone Relay extension in it.  This has no switch inputs, but has a number of switched outputs.  This is required as there are so many lighting circuits in this part of the house (the kitchen alone has 7 lighting circuits).  The next module is an 8V 1A Friedland door bell transformer which is used to operate the door latch release on the back door.  This is activated using a key fob, fob reader and One Wire Loxone extender.  Although the Loxone Extension units can output 10V, there is not enough current to operate a door latch.  Lastly, in this top distribution board, there are a number of breakers that would not fit into the main distribution board.

The middle distribution board houses the TDK 24v power supply for the Loxone kit, a single Loxone Extension and a Loxone Dimmer.  The dimmer will centrally dim up to 4 separate lighting circuits.

The bottom distribution board houses another 2 Loxone Extensions as well as a DMX controller and a One Wire Extension.

At the very top of the unit, is the receiver for the Owl Intuition smart meter.  This connects wirelessly to the transmitter on the other side of the wall (connected to the electric meter) and is this connect to the Internet via out network.  This posts up data on our electricity usage every 15-20 seconds.  You will find more about this here or on the Owl Intuition website.

This shows the layout of the Loxone kit in the newer part of the property. It houses 3 Loxone extensions, a ,dimmer unit, a DMX extension and One Wire extension. There is also the receiver for the Owl Intuition smart monitor (the transmitter for this is on the external side of this wall attached to our electricity meter).

Monitoring energy usage with Network Owl

March 14, 2014 /

We have just installed a Network Owl to monitor our energy usage.  This monitors the power being used on our incoming electricity supply and uploads the data to the internet.  We can then monitor power usage from anywhere and (pretty much) in real time.

We have a 3 phase supply and are using a Network Owl and Owl Intuition-lc.  This solution is intended for home and light commercial premises that are on a three phase supply.  The hardware is under £100 and it took less than 30 minutes to set it up.

Creating an online account to view the data is a little quirky, but if you follow the instructions carefully it doesn’t take long.

Having installed a ground source heat pump, all of our heating and domestic hot water is essentially electric albeit aided by extracting heat out of the ground.  So we thought it would be important to having an understanding of the amount of power that we are using.  This solution looks promising and I am somewhat intrigued by the numbers.  By combining the data from the Network Owl with data from our weather station and internal temperature sensors, we should be able to get a reasonable understanding of the heat performance of the house.

Once you have the network owl up and running, you can view your power usage in real time via the web. I only installed it yesterday, so it is a little sparse in terms of data.

As well as getting an overview of power usage, you can also see more detailed graphs as well as downloading the data into Excel (CSV format).

This is a small device that connects to your router (Ethernet connection on the right, power on the left). It connects wirelessly to the sensor box with the three sensors that are clamped onto the incoming 3 phase supply. It then uploads the date to the internet where you can access it online.

The sensor box is installed in the meter cupboard with three sensors - one onto each of the incoming live supplies (we have a 3 phase supply). I may move the sensor box and sensors to cables inside the building as it will be warmer and kinder to the batteries (as well as improving the signal strength to the Network Owl).

The sensor clamps are very easy to install and only loosely clamp onto the cables. You just need to remember that this is a live supply that you are dealing with!
