But I like a lot about this device. One is that it has an open API, so you can actually build your own software. It gives you your regular index for air quality, the air quality index, and then it gives you your PM 2.5, which again matches pretty closely with what we've got here all right. So I've been talking a lot on social media about how much I like this device.

It's called the laser egg, it's by a company called kite era, and it does a lot of different things right now. It's showing PM 2.5. It shows co2, which is one of my favourite things, to look at inside of a home because it really kind of tells you something about ventilation, and you can see right now we're in the good zone and then it also measures humidity and temperature right now. It's showing a ridiculously high humidity, because I'm touching the thing and messing with it so laser it connects just using a USB micro kind of standard connection.

I've been checking it against this device. The timtom M mm C, as well as the IQ air, as well as a bunch of other IQ monitors and the PM 2.5 in the co2, remains pretty close between these two, because I've been messing with them right now. It's kind of jumping around, but I like a lot about this device. One is that it has an open API, so you can actually build your own software.

It gives you your regular index for air quality, the air quality index, and then it gives you your PM. 2.5, which again matches pretty closely with what we've got here and then it also gives you your co2, like I mentioned, but one thing that I wanted to try to figure out was how to set this up. So that way, it would bring on either a ventilating dehumidifier, maybe a fresh air damper or a ERV in order to automatically compensate for high co2, and I was able to do that using a couple pretty easily found consumer devices, one of course being the laser itself And then, the next being a Apple home, compatible outlet which I'll show you here in a second made by Belkin, but there's a couple different ones and it doesn't you don't have to just use Apple home. You can use the Google home assistant or Amazon Alexa, whichever you prefer, and then I just plugged it into my gr V, but you can use it on basically, whatever you wanted to do it with.

If you wanted to do with a fresh air damper, you could rig it up with that and a relay you could do it with a ventilating dehumidifier as well and depending on your application. You know. You're gon na have to make some different alterations, but I just want to show you what I've done. So this is what the laser a-gap looks like.

I chose the laser ik plus co2, because co2 is what I want to use to control my ventilation and after tracking it. I found that at night I was getting a lot of spikes of high co2 in different rooms, and so I already had an ERV on my house. I actually hadn't been using it recently because in Florida, RVs aren't necessarily the ideal situation, but I wanted to go ahead and hook this up so that way he would bring on bring in outdoor air on demand, and you can actually see when the ERV came on. My co2 levels dropped quite a bit when I brought it on my PM 2.5 levels.
My particles came up quite a bit so bringing in that outdoor air did impact the amount of particles that are brought in, so it was a little bit of a trade-off, but the way I did it was actually pretty interesting and this tight air laser egg allows Me to do that. If you take a look in the settings, I can set the co2 threshold. I've set it at a thousand, but I can adjust that and in fact I think I'm gon na go ahead and adjust that up to 1200 and so homekit will be triggered when the co2 exceeds this threshold. So now all I have to do is leave the kite era app go into the home kit.

App and now I have this automation, setup and the way this automation is set up is that it will turn on the ERV when we have high carbon dioxide detected in the master bedroom. Now it doesn't allow me to set the level because that level is set in the laser a gap already what that means to have high carbon dioxide. I can set it for certain times a day if I want - or I can leave that at any time, which is what I currently have set it's likely to go on at night. So if I breathe on the device, it'll actually turn on my ERV, I can.

I can show you kind of how that works here in a second, but then it will stay on and it will shut off after our once it just come back down again. So that's the way that I've decided to set it up. I've been fully tested because the question is: does it run for a full hour and then shut off automatically or does it shut off automatically once the level has been achieved below that point, and I believe that's how it is, I think, based on the testing, I've Done so far, it seems like it keeps it on as long as it's above that threshold once it drops below the threshold, it runs an additional hour which is sort of my desired setting. I can still adjust that a little bit more.

If I find out, that's not how I want it by changing the turn off time, but you can see, I could add more automations here as well. I could add automations, for example, if I wanted to have a air sensor quality, I could bring on a HEPA filter if the air quality drops below excellent, for example, at night. If I wanted so it gives you quite a bit of variability, it allows me to select what I want to have it trigger now. Currently, I only have the ERV, but if I had more options, I could trigger a extra filter for that matter.

If I didn't want to run a PCO type device all the time, I only wanted to run it when indoor air quality was bad. I can bring it on under those circumstances, a lot of different options that we could use here. So I think it's I think it's interesting. I think it's useful again.

This only works if you have some sort of Apple Apple hub device, in my case, I'm using an iPad as my hub and of course you have to use Apple devices in order to utilize. This functionality do similar things with other. You can do similar things with Android using Amazon, Alexa or Google. As far as I understand I just haven't, tested those out yet, and I am working to create a universal solution for this using laser egg and a Raspberry Pi.
This Belkin Wemo adapter, is what I use it's actually an outlet, there's the apple homekit, there's the point that you scan when you're using to set it up with apple homekit or whatever you're setting it up with there's some different methods depending on the setup. But that's what I use it's real nice, because it hasn't blocked the other outlets and it's very easy to set up. So this is called the Wemo mini smart plug. You can see you download the appropriate app and either the App Store or Google Play pretty much.

Just plug the thing in you connect, it creates its own little Wi-Fi that you connect to in order to set it up with Wi-Fi and it works with Nest. Apple homekit, Google assistant, and if this than that for control, why the only one I've tested it on his apple homekit, and it worked really really well for that. But it looks like it also works with these other options. If you don't use apple homekit in order to utilize apple homekit, you have to either have an iPad, a newer Apple, TV or a.

I think they call it home pod or something like that. That gets Atticus Apple home pod in your home, I'm using an iPad as my kind of central home kit hub alright. So here we are in my daughter's closet, where the erv lives and we're gon na go ahead and do a test and we will trigger the laser egg by breathing on it and see. If it brings on the automation and brings on the ERV, you can see got ta plug it in here to my Wemo.

So let's see what we got. Actually, co2 is pretty good up here, but I'll just go ahead and read on it and see how responsive this thing is. It'll it'll jump up pretty quick. Now, once it gets up above 1200 there it goes there we go.

I don't know if you can hear that, but my ear view just came on now. This will slowly start to drift back down the air quality warning just went away. It went back to fair, it's still triggered on carbon dioxide. Here we go just went below the threshold, but it's still staying on because it's got the hour limit, so this will now stay on for another hour before it actually shuts off to bring it all the way down, so that is Wemo from Belkin as a plug.

This is the Apple home, app I'm using an erv, but we could just as easily do a ventilating dehumidifier we've got or a damper for that matter with the Wemo it'd be interesting. How you would do that? I think in that case you would maybe use a plug-in transformer go down to 12 volts or something or you could just use a relay. They make relays that can be driven by an apple homekit as well, and then the laser egg from Chi Terra, which has lots of interesting applications all right. That's it for now demand ventilation using the laser egg.
Thanks for watching catch you on the next one.

    Hey Bryan have you tested the uHoo IAQ monitor for accuracy? Nice to see a different way of using the products available. Using Nexia, April Aire dehumidifier, 8” damper for fresh air piped into the dehumidifier, uHoo and IFTTT at my house.

    Finally somebody figured it out!!!!! You are the man!

    Particular problem when your ERV Come on that’s why you’re going to install that massively oversized ( or unmeasurable static Pressure loss, true commercial overkill HEPA filter in series with your ERV when it comes on.
