I am working on a HVAC zone controller now. I shelved it about a year ago but have been meaning to pick it back up again. I have one working based on X-10 thermostats but wanted a single device to sample temperature as well as control the dampers. The motorized dampers I am using have been running for years without an issue. There will also be a moisture sensor as well. The device will be quite cheap to make. My biggest issue is controlling the device from each zone location. I got sidetracked by that. I wanted a simple and cheap touch pad that would fit into a j-box.

Users / Re: CT100 ZWave Thermostat Fahrenheit vs Celcius
« Last post by davegravy on Today at 06:45:22 pm »
Manufacturer responded by referring me to support for my Zwave controller.

I responded:

Perhaps my question wasn't very clear.

Your thermostat interprets commands sent over Zwave and modifies its settings (example heating termperature setpoint) accordingly. The means by which it interprets those zwave commands is what I am questioning, and is irrespective of the Zwave controller.

The zwave controller manufacturer will not be able to help me with this and will refer me back to you.

Please tell me if there is a way to change the behaviour of the CT100 so that it interprets temperature setpoint changes received via Zwave as degrees Celsius as opposed to degrees Fahrenheit (note that I'm not referring to the display units which is a different matter).

I'm not very knowledgeable about how these devices talk at a low level, but I'm assuming there is no unit (Celsius/Fahrenheit) supplied with setpoint commands by the controller, just a value, and that it's up to the thermostat to interpret it as Celsius or Fahrenheit (obvious design would be to decide this based on the unit that the user has chosen to have displayed on the LCD of the screen).

I'd be interested to hear more about what your doing with your MSP430G2553 based micro controller both in the garden setting and at the end of your drive. Both sound very interesting indeed.

Hi Andy

Sorry just saw this. I have 2 devices so far. The 1st one is a switch and input device. The switch drives some 12 volt relays that can switch up to 120v ac but with a small amp rating at 120v ac. Great for irrigation or a gate etc. It could be coupled with a contactor for more current if needed. The inputs are digital (for now) that can be connected to say a rain sensor or a photo eye. I have some vehicle loop sensor connected. I am working on analog devices now like temp and moisture. Pretty straight forward.
The 2nd device is an audio switch that uses digital switches. The one I have take 16 inputs and can switch it to one or all of 12 outputs.
If you can make your own PCBs (which is pretty easy) the costs are very cheap for the switch. The audio switch can get pricey with each of the digital switches around $2.50US each. You need 1 for each output zone per channel with 8 inputs max. So 4 chips for each output zone for my setup with 16 inputs. This could start small and chips added as needed to keep the cost down.

I do have some extra PCBs if you are interested. I had some made in China.

I just started to work on a touch screen controller for lmce. Not an orbiter but basically a switch that would be tied to events. trying to get it to fit in a j box with a standard decora plate.

Sorry for the late reponse

Does the log still show similar call activity now?

Actually it does. Any ideas what might cause it?

Users / Raspberry Pi Model A+ Experiences
« Last post by totallymaxed on Today at 03:48:52 pm »
I've been testing some Raspberry Pi Model A+'s over the last few days and wondered if anyone else had been too?

The Model A+ is about half the size of previous Raspberry Pi's but has the same mounting holes (at the same centres) as the earlier models. It lacks the the LAN port, only has a single usb port and only 256mb of RAM. But in all other ways is totally compatible with the earlier models - I could boot a test Raspian SD card from a Model B on the A+ without modifications.

The Model A+ uses the same Application Processor as earlier models, has 40 GPIO pins, far better audio quality (uses a separate low-noice power supply) which is great for SqueezeLite applications, power consumption is about 25% less than the Model A. Then there's the very low price - $20 USD + Tax & shipping.

I've been testing the Model A+ with a usb wifi adapter to get it connected and this works really well - again just like previous Rpi's. The only area where the Model A+ falls short is running something like XBMC where the 256mb of RAM is a little on the light side. But for SqueezeLite its pretty much perfect and for everything else the Model A+ is a great choice.

Anyone else got a Model A+? Any feedback, experiences or views on it yet?

All the best

A simple test would be to temporarily disable the external trunk and see if the phantom rings still happen.

doesn't that previous message already answers that option?

Actually it does...I hadn't noticed you mentioned disabling your provider. Glad the rings have stopped...and I hope they don't return! Does the log still show similar call activity now?

Command/Query examples; Standby ON/OFF, Input Select, Vol UP/Down, Mute, Status, Vendor ID
- “Unregistered” if it’s the initiator address, “Broadcast” if it’s the follower address.

For LinuxMCE users you will need to create a custom GSD device to provide access to CEC control on your system. We provide details of how to create one yourself with each license. We are also working on a CEC GSD device that we will provide as part of your license that you can add to your system. The RaspCEC-Pi LinuxMCE GSD device should be available shortly and will be made available to all customers a no cost.

Install our RaspCEC-Pi firmware on a new Raspberry Pi Model A+ with a usb wifi adapter and use a spare usb port on your TV to power it.  No power adapter or CAT5 cables to run. Get full control of all the devices attached to your TV's HDMI ports anywhere in your home without needing to run any cables at all.

Any questions please contact me here by PM or email me here; inquiries@ellipticalcurve.com

All the best

A Series Highlighting How to Configure your Dianemo System

With the availability of good quality Wifi 802.11g/n routers & devices in recent years using wifi to connect your devices to your Core/NC has become a reliable solution. There are many situations where running new CAT5 cables in a property is not possible. It might be because the property has been recently re-decorated, the property might be rented or it might simply be that you just don't have CAT5 in the right places. In all these situations and many more too using Wifi is a viable solution in the vast majority of cases.

In smaller properties, or apartments, a single wifi router may be all that is required to get good signal coverage. But in larger properties you may need to consider using wifi extenders to extend the range of your wifi LAN to more distant locations. Wifi extenders are readily available now if you need them and are very affordable too.

The main advantage of using wifi is that you can locate your wifi device wherever you have a power outlet. Below a TV or Audio Amplifier for example or in the case of devices like Raspberry Pi's tucked behind the equipment you need to send audio to or control is possible too.

As a company we have a lot of experience with wifi in installations through both our professional installers and software license customers. I have several Raspberry Pi's around my home and they are all connected over Wifi. In my case i'm using wifi connected Raspberry Pi's for  CEC control, XBMC video and SqueezeLite audio. We have customers who also have SmartTV's connected over Wifi too.

Clearly if you've invested in CAT5 to each room then use it. But if you haven't or if you forgot to run that now very important last run of CAT5 to a guest room then go with Wifi for sure.

If you have any questions about wifi in general, Dianemo, Raspbmc-CEC, RaspSqueeze-CEC or RaspCEC-Pi then please just PM me here or contact me at; inquiries@ellipticalcurve.com

The new Raspberry Pi Model A+ combined with our RaspSqueeze-CEC or RaspCEC-Pi firmware is perfect for discretely tucking away where you don't have any CAT5. Simply add a usb wifi adapter and you have the smallest most energy efficient audio/CEC control solution there is. See below for more details;
