content: My friend is in the team of guys developing device that turns regular AC unit into a smart one.https://www.indiegogo.com/projects/monolyth-smart-device-for-window-wall-ac-unitsPlease back them if you could use a smart AC unit.

Feel free to post them to Indiegogo as well.- the device itself runs on a ARM cortex M3, so the power consumption should be minimum (<5W). Of course we'll do the mesurements when we get the final PCBs from the production.- the app is, let's say, in development. First we have to finish the HW part (pcb+firmware), then we plan to wrap up the app. It's the easy part.We've been in SmartHome business for quite some years now, we have our own brand, so we have a lot of experience in this "device-cloud-app" field.- the "40%" figure comes from various studies, that you can reduce your energy bill if using "smart" management. Of course the figure will vary on how much diligence you allready have, but the "average user" will, for example, turn on the A/C and just leave it running... with a combination presence and geofencing we can detect you went to (let's say) a store for an hour and therefor turn off the A/C automaticaly.Regars,Peter

content: Quote from: mojo-chan on July 08, 2014, 08:19:05 amMaybe I should make the answer more clear: <5W was related to max power output (thought you were interested in that, sory). Of course you won't be using 5W 24/7, but until I do some more measurements I can't say about Idle power usage as the firmware is stil being developed. (using sleep cicle routines for mcu and sensors will drop the power usage significantly, but the optimisation is still to be done)Just as a discussion, what would (for you) be an acceptable power usage for a "gadget" that you plug in and leave it powered on? For example at 0,1€/kWh constant 1W would cost you 0,88€ per year.QuotePoint taken.Of course it's not enough to "pay" someone to develop the app, backend and build the circuit. We ourselves have made huge investments allready (webpage, promo video, first few prototypes, lots of sensors,...) and are planing to do so in the future. The point of us going to a crowdfunding platform is to get some funds to start a production. We plan to keep the Monolyth as a product and put it on the market to make some real money.If we get the funding, the app will of course be available when we'll be shipping the packages.QuoteIt is true, that even a cheap PRC air conditioner will have some basic options. Many allready have timers. Some even support scheduling. But if you do some polls, an average user won't use it, or at least, not to it's potential. In the era of smartphones and tablets you "should" have an easy-to-use app and some algorithms to automate the process of setting the right temperatures. The point of our "device" is to optimise your a/c behaviour, using the features that it allready supports naturaly. So I don't know, why would it waste power, in case you would disable all the Monolyth's smart features, you would still gain remote control and graphs, which is a cool feature, don't you think?Will get back to you with the studies quotes.Regards,Peter

content: Daikan have some clever ideas.Intelligent EyeThis is an infrared sensor with the ability to sense movement. When in the room, the air conditioner operates normally, but should you leave for more than 20 minutes the air conditioner automatically changes to an energy efficient operation.Then there isNestthermostats. Im not sure if they only control furnaces for heating, rather than aircon.The last thing you might want to investigate is if the other companies have patents, etc.

content: Just getting the IR codes to control all types of AC/heatpump units out there and verifying they actually work is a massive undertaking.So many devices have annoying quirks when trying to control them without any feedback as to the devices current state.Some units even use a RF 2way link instead of IR so that the remote can know what the AC/heatpump is actually doing.

content: Quote from: nowlan on July 08, 2014, 10:10:57 amNest can control both heating and central AC. It cannot control window AC units. It may be able to control some wall mount  ones, that support a traditional thermostat interface. The Monolyth appears to be aimed more at the retro-fit window and wall mount AC units that are not tied to the household heating controls. It also appears that these units require an IR remote control interface to work with the Monolyth -- something that most permanent units don't have.

content: Quote from: mojo-chan on July 09, 2014, 09:00:14 amSorry to be clear by permanent [in the last sentence] I meant the central air type where the evaporator coil/heat exchanger is in a forced air furnace, this type typically does not have an IR interface. The wall mount and window units, on the other-hand quite often do have an IR interface.

content: Just some thoughts...Each manufacturer has diferent IR codes, even different regarding diferent models. We know, this was actualy one of our first chalanges, so we've been building a database (scanning remotes) of those for various A/C's for more than 10 months now. Couple of hundred and counting...There various types of heating/cooling units available on the market. We are targeting the Air conditioners, that can be controller via IR remote control, which is, by our data the majority of cooling units available.As for the comparison with Nest: it is ment as a replacement of existing (wall mounted) thermostats. So, it's a solutoin for wired systems - it can be used for cooling with fancoils, let's say, but not for IR controlled A/C units.Regards,Peter

content: Guess what I can do for $0?Turn up the A/C when I leave...Turn down the A/C when I come back...Material required: 1 finger.Time required: Milliseconds.Effort required: Minimal to none.Intelligence required: Minimal to none.That should be crowd fund-able by the moronic masses...

content: Can I set a target temperature and time, and let the "Monolyth" figure out the AC settings to get there?(Not that I'm going to order one for January delivery... I'd say that was poor planning.)
