    Anyone interested in discussing building DIY Home Automation software and hardware?

    Here you go:   Firmware Drivers V2.1.0 from Semtech.   These drivers are written in ANSI C so should run on an Arduino without much modification. If you get stuck, just let me know and i'll be glad to help.   Listen mode isn't covered in the library but it can be added. The big difference...

    Anyone interested in discussing building DIY Home Automation software and hardware?

      Thanks for pointing it out. I think the device is a very good find so well done as it's going to give the EFM32 a run for it's money.   I couldn't find availability for most of the parts on digikey or octoparts and the Atmel website shows 0 stock through distributors so I wonder what the final...

    Anyone interested in discussing building DIY Home Automation software and hardware?

    Those power consumption figures, if true, are quite impressive so you've peaked my interest. Such low power consumption figures are great for energy harvesting home automation technologies such as passive sensors but less useful for active devices that need to run constantly to route packets.  ...

    Anyone interested in discussing building DIY Home Automation software and hardware?

      Not me but the dizzying array of options makes my head hurt. I decided quite some time ago to go with an architecture, for better or worse, and I've been quite happy.   The PSOC 4 is one of those extensible architectures, like the FPGA merged with an ARM M series CPU. Quite cool and very...

    Anyone interested in discussing building DIY Home Automation software and hardware?

      Thanks for the link. I'm really enjoying the site, specifically arduino hack article and the low power regulation discussion.   An approach I've been using successfully to manage peripheral circuitry current consumption for sensors is by using a FET high side switch. For my temperature and...

    Anyone interested in discussing building DIY Home Automation software and hardware?

    Hi NeverDie   I look forward to seeing how 2.4GHz feeds into your HA setup and more specifically, battery life.   This conversation will be a bit technical so I hope that other Cocoontech readers see we're trying to improve RF reliability and transmission range i the 2.4ghz spectrum for HA nodes...

    Is HA a solution looking for a problem?

    Hi Deandob   At this time it's just for my own use so but it has a name 'Nimble Cirrus' and I think it could have broader appeal given the simplicity of design. Unfortunately I feel HA is really in need of a solid problem to solve so it might not be commercially viable for the masses. I'm always...

    Is HA a solution looking for a problem?

      Hi wkearney, what needs to be done to move automation forward? I can see many things about the current state of HA, namely usability and simplicity, that need to be improved. Is privacy a reason for users not adopting HA in droves?

    Anyone interested in discussing building DIY Home Automation software and hardware?

    Never     LOL, I really enjoyed reading your story and could relate to it 100%. If you end up commercialising your ideas then I guess you can just re-visit your design or opt for the originals.   It's possible however that the range problem you experience with the original Nordic chips and other...

    Anyone interested in discussing building DIY Home Automation software and hardware?

        Hi NeverDie, this video about noise and digital oscilloscopes might be helpful. https://www.youtube.com/watch?v=Znwp0pK8Tzk   Thanks for the link. I enjoyed reading the analysis and investigation you're doing on the mysensors forum. Of concern are the fake NRF modules on sale. The one with...

    Is HA a solution looking for a problem?

        I really think you're onto something with the industrial design comment.... many of the devices I see in the HA space are very functional but less aesthetically appealing. I put a lot of work into the industrial design for my HA product set so that the wife would like it in the bedroom and...

    Is HA a solution looking for a problem?

          The thing with solutions looking for problems is that from time to time, people don't realise they like something or that something is a possibility unless they taste it, try it, see it or use it. 'We don't know what we don't know". That's where I think home kit will help because they'll...

    Is HA a solution looking for a problem?

        I too have to defend my decision to automate but i'll do it willingly because I love the technology and see possibilities. In contrast, my wife just wants to turn the lights on whereas I hate paying for excess power consumption when I don't need to so would like the lights to turn off by...

    Is HA a solution looking for a problem?

    Hi All,   I've been reading this forum for a while now and have found a couple of excellent threads that discussed what's new over the last 7 years and the frustrations with HA but no specific thread about the real-world problems that HA actually solves.   Having built my own custom HA ecosystem...

    Anyone interested in discussing building DIY Home Automation software and hardware?

    Firstly, congratulations on buying the Rigol DS1054. In my opinion, it's value for money cannot be beaten! I have a similar scope from the same manufacturer that I hacked so that its bandwidth was boosted to 300MHz instead of the 75 it came with. Rigol manufacture exactly the same probe front...

    Anyone interested in discussing building DIY Home Automation software and hardware?

    Mine also arrived without instructions and it was challenging finding information about it. Annoying because its not cheap. Here's something from the maker: http://www.eevblog.com/projects/ucurrent/   I sit corrected, the voltage swing on mine was in the mv range, not v range so I don't think...

    Anyone interested in discussing building DIY Home Automation software and hardware?

    That's disappointed for you. I don't get any noticable noise measuring voltage drop with my scope so without actually seeing the setup, I'm not sure what to say.   You could try putting balun filters on the VDD into the NRF24L01 to knock out high frequencies. If you haven't already tried, switch...

    Anyone interested in discussing building DIY Home Automation software and hardware?

    Hi NeverDie   Compared to Arduino, mbed is probably at the same level of complexity and supports or the usual peripherals... interrupts, io, motor controls, sensor interfaces so I would be too concerned about it. I began with Arduino but have been happy using mbed.    I've not used ST devices...

    Anyone interested in discussing building DIY Home Automation software and hardware?

    It was a really smart purchase because energy micro was the only ARM fabricator that architected an ARM based chip designed specifically for low power consumption. While the other companies talk about low power, I would be pleased to know about any device that offers the same level of fine...
