 Mwneud y byddwch, mae'n gwellio bod yn dweud eu bod yn cyd-dweud, a rwy'n gweithio gyd yn ffasgau'r ffordd yma, dwi'n fwrdd i'w ddweud o'r ffroedd ymlaen nhw, ond rwy'n dweud, ac mae'n meddwl bod y ffraith o'r ddechrau ond y maen nhw'n gweithio'n ffordd. Mae'n rwy'n dweud o'n dweud o'r ddweud. Here with Tristan Lee and we both work full-time on the Open Energy Monitor project, a project to develop open source energy monitoring tools. We got inspired to set up the project. Can I just put a little light up? Is that going to be okay for the video? There we go. We're inspired to set up the project because we're interested to try to better understand our energy consumption and generation and make informed decisions with regard to how we use our energy and how we can optimise our energy systems. So that's the system in its current state. We've got various RF wireless nodes, web connected base station and a cloud-based web-based login and graphing service. These are the current hardware units. All open hardware, all based on mainly on Arduino for the wireless nodes and we used Raspberry Pi and standard Raspberry Pi software for the base station. So our latest unit is combining the base station and the energy monitoring node to all in one into a unit we call the Emon Pi, which is a Raspberry Pi based energy monitoring unit. You can also receive other data from other RF units such as temperature and humidity nodes. As well as posting to EmonCMS.org, our cloud-based service, it runs a full web server and runs EmonCMS locally, so if you wanted to, you can keep your data all in-house. I'll talk more about the software running on here later on. Ac mae'n ddysgu'r droswyddon EmonTX ar gyfer ei maen nhw'n gweld, rhai mwy ffordd gydig ym Mozart.

On the software side of things, Tristan's done a lot of work developing EamonnCMS.org and EamonnCMS is a login and graffing platform designed primarily for power but any sort of environmental data, temperature, humidity, you can throw at it. I'm a hosted version at EamonnCMS.org but it's fully open source so you can download it and run it off any Linux server and we get some amazing community development contributions to this part of the project now. Once the data is in EamonnCMS, you can do some pretty dashboards showing how much you're using and if you've got a solar PV, how much you're using from your solar, how much you're importing and that sort of thing. I mentioned the community, even though we're quite a small organisation, Tristan and myself and we have a couple of other people helping us with manufacturing running the shop. We've got some amazing community members so we get lots of open source contributions from various people over the world which is really very nice. This is an example of a community contribution. Someone contacted us saying we're written an EamonnCMS Android app. Would you like it? Can we launch it in Google Play Store? Of course we welcomed it with open arms. This is in the Google Play Store now. It's a nice EamonnCMS app for Android. We both live and work in North Wales where we grew up there. We're still living there. We're very happy to be able to do the sort of work and live in what is quite a remote mountainous location. It's fantastic to run an open hardware business from here. We've always made a thing of trying to manufacture our units in the UK. Now we've manufactured a factory just down the road from us, 15 minutes down the road from our office. It's great to build, to pop down, chat with the guys there in Welsh who run the pick and place lines like local guys. It's really great to catch problems early on, like a really tight feedback loop. We were inspired to set up the project to help people save energy and reduce energy consumption. We found ourselves manufacturing electronic hardware, which is not a particularly low energy intensive thing to do. We were interested in looking at the embodied energy in our units. This is going off a bit of a tangent, but it's something that we're quite interested in. We were inspired by the Fair Mouse project that then led on to the Fair Phone project that you might have heard of. You do? Oh, awesome. I've not seen one in the flesh. That's a fantastic project. Amazing. That's what actually inspired us to try and do some of this ourselves. There's obviously a really complex task with lots of things that feed into it. We thought we would try and produce these figures that were taken from data sets that we could get our hands on, which need to be taken with a pincer cell. It's a very interesting process to go through and highlighted some things that we thought, for example, a quarter of the entire embodied energy is the power adapters and the sensors, and a quarter is the enclosure. That bit there is all the electronics that we manufacture. From that, almost half of that is the PCB design. Smaller you can make the PCBs, the better. We came up with this figure of 40 kWh per day of energy it takes to produce. Assuming you might be able to get a 5% reduction, maybe more, it should pay for itself in terms of energy. It gives the amount of energy used to manufacture within three months of being installed, which is quite a good thing, but it's obviously still room for improvement. One thing we do do is we make sure we ship all our power adapters and CTs that we buy in China via to the UK, via ocean freight on a pallet to make the embodied energy as low as possible. That's 19 times less energy to your ship via ocean than air. It doesn't stop there. We obviously need to ship it to our customers. If our customer happens to be in Australia, then in 2014, 5% of our orders went to Australia. That used as much energy as 75% of all the EU orders. 75% says quite a lot of energy. It made us realise that it doesn't really make sense to ship power adapters from China to the UK and then back to Australia. Maybe we can look at getting it just to be there. We're good to get more orders from Australia, but interest the exercise anyway to get a grasp of these sorts of things. That's a bit of a tangent, but it's all related really. Bring it back to energy monitoring. Now we have the ability to monitor energy, which is great. What are the next steps? How can we make this data useful? How can we use this data to inform decisions that we can take? These are some of the questions that we've been asking. The first few are easy to answer, like how much energy do I use? Things like how can I intelligent control my heating? How can I look at when is a good time to do my washing or charge my car today based on grid carbon intensity? To do these sorts of things, you often need to interact with other systems and be able to pull in data from other systems which got us to put more work into how we can make our system as open as possible in terms of APIs and data formats and how we can also interface with other systems. This is where two things you're probably most people are familiar with here. MQTT and Node-RED, two amazing tools to come out of IBM. I've been calling these two things the glue of Internet of Things. You can pretty much connect any Internet of Thing thing to another thing with these two things. So we wanted to make both these things integral to our system. We already used MQTT on the E1 Pi, but on the latest software stack we've put effort into making the protocol as interoperable as possible with other devices. So the E1 Pi runs an open MQTT server, authenticated, but open port. So any device on the network, if it's got the correct authentication details, can connect in and listen to the energy data and advice first. If you want to post anything to E1CMS, you can just post to this MQTT server running on the E1 Pi and it'll appear in E1CMS. On the latest software stack we build fully E1 Pi, which is a pre-built SD card image, has got Node-RED and OpenHAB, which is an open source home automation system all running and configured as standard on E1 Pi. So if you do want to use Node-RED to say pull in data from somewhere exotic or I use it to pull weather data from weather underground, feed it into E1CMS, that was just a few drag and drops away. So we want to make it as easy as possible for people to explore doing these sorts of things. Also running on the box is a lightweight RF plug control, which to enable to control RF plugs to switch appliances on and off. So we've been thinking about more as E1 Pi, as it's got full Raspberry Pi 2 in there. So just log in a few power values, it's much more capable computer to do a lot more. So we're thinking about it as the home hub running, easy to set up but easily expandable to do more complex things if the user wants to. By default it logs locally, but there's also the option to log to E1CMS.org, our cloud-based server, from remote backup and remote access. So we've been working with Martin Hrysinoff, this is kind of leading on from the MQTT to control side of things. He's produced an MQTT Wi-Fi really, that we will be selling through the shop. He's controlled by MQTT, and he uses the ESP8266 chip, and it's amazing what he's done with this chip. He's running a full web server off there with a nice little thermostat scheduling UI that Tristan wrote a few years back that Martin's taken. This relay is really useful for Tristan O'l Cymontor, he's been recently installed a heat pump, he's been using the relay to be able to control that. This was a slide I put together earlier just to explain to the OpenTRV guys. The standard MQTT topics that we use is Emon as the base topic, and then the topic names informed the EmonCMS feed names. So if you say posted Emon, then EmonTX and PowerOne, and then whatever value you are monitoring, that would result in a feed input being made in EmonCMS called EmonTX and PowerOne. So if you wanted to post to the Emon topic and anything else like Emon, forward slash, upstairs, forward slash, temperature, and then your value, that would just appear in EmonCMS inputs. To make it easiest possible, so you can discuss if you're interested in getting one of these values into another application or you need to subscribe to the topic that you're interested in and pull that data value. This was just an example of the use I've been making of MQTT on my EmonPie, I've got various publishers, EmonPie being one of them, my heating controller, OpenHab all going in, and Node Red sitting there in the middle. This was a real simple example of how we use the Lightwave RF, which is to communicate with these Lightwave RF plugs. So if he sends like a one to the Lightwave RF topic, that will turn the plug on, he sends a zero, it will turn the plug off, and all this is set up and pre-configured on the EmonPie and works out the box to control once paired with obviously any Lightwave RF plugs. It's a really easy way to control appliances. This was a screenshot from a demo I did last time I was giving this presentation at a tech talk up in North Wales at Christmas time as you can see, and my girlfriend was home at the time and I was having good fun switching the lights on and off just to demonstrate the Lightwave RF plug control. And at the same time showing the raw MQTT data topics floating by and the EmonCMS myelectric map updating in real time. So I'm going to hand over to Trista now, who's going to talk a bit about the heat pump application specifically that he's been working on.
