Topics in Home Automation - New Article in Residential Tech Today
My latest article, "Managing a Home¡¯s Air Temperature Based on the PMV Comfort Model¡± is being published by the good folks at Residential Tech Today Magazine on their web site.
Since the development of modern heating and cooling systems for homes, people have managed their operation by simply selecting a temperature "set point".? However, that approach doesn't focus on what is really important; whether the occupants of the home are comfortable, or not.? This article looks at the practical application of the American Society of Heating, Refrigerating and Air-Conditioning Engineer (ASHRAE) standard 55 which focuses on thermal comfort instead of set points when heating / cooling a home. You can find the article here: For those interested in earlier articles that I've written, you can find those here: Finally, for those that want to see even more content I've written about smart home technology you can find that here: Thanks |

Re: Cheap reliable power monitoring.....ya right.
Many of the current generator installs they have an on board or add-on I/O and Relay board that can be programmed for various faults/statuses (Kohler calles it a PIM for example). We always tie into those and feed our processor to get running status/fault status/low battery/etc.?

Seura Shade 2 RS-232 control
Hi All,
I'll be working on a project with rs-232 control of a Seura Shade 2 TV and have the protocol doc. it lists the following for the start and end characters: ? Start with 0x02 (hex)
? End with 0x03 (hex)
The example for Power OFF is:[0x02]PWD:0[0x03] For those who have dealt with this product, do you think the format should be: \x02PWD:0\x03 or [0x02]PWD:0[0x03] I'm thinking the former, but of course anything is possible in this realm! Haha TIA! |

Re: Bond Bridge
I have one controlling a few different brands of fans plus some RF shades in the house. Jay's module works well, but I also have an ISY-994 controlling the same fans with some pretty simple commands.
This might help you out, though it's not Creston based, it's what I'm spitting out of the ISY. The only problem might be is if the fans have a discreet power off command or not. They'll usually turn on with a speed command, but of course power off will be problematic if the fan's power switch is a toggle. PUT /v2/devices/<device #>/actions/TurnOn HTTP/1.1
Host: 192.168.2.71:80

I don't think it would be too difficult to write up a basic S+ module to control the fans, just dig into their API a bit to find the power and speed command actions. ? |

Re: Cisco Widgets - OS10 vs OS11
Update...I received a Codec Plus with OS11 and was able to check this myself (previously was working with a tech in the field). What I found is that, unlike 0S10, with OS11 if you have a Cisco widget on more than one panel (in this project it included both button and spinner widgets), the feedback only works on the first panel to appear. Any subsequent panels that are triggered to appear that have an identically named widget will only provide the button press from it and it will not receive feedback.
The reason I have more than one panel on the Cisco touch screen with the same widget is because this is a divisible conference room and, when divided, the divided audio control panel shown in room A does not include mic controls for mics dedicated to Room B. This is done by properly hiding and showing the panel trigger buttons based on the room mode (divided or combined). I fixed this by creating new widgets for the second panel and dovetailing them into the same programming the widgets used in the first panel. I am going to alert Cisco of this difference in OS10 and OS11. Hopefully they can go back to having it work like it did in OS10 with a firmware update.? |

Re: Bond Bridge
¿ªÔÆÌåÓýI don't personally use the Bond bridge or Bond bridge pro in my own home.? However, I did write a Crestron driver for integrating them with a Crestron system including the use of Bond Sidekick keypads. The driver is on my GitHub here: Hope this helps Jay On 7/17/2023 3:57 PM, FTAV wrote:

Re: Bond Bridge
The Bond Bridge Pro is incredibly reliable and has a great range. I've had the same issues and I'll always?install a Bond Pro. I'm in a high-density area in downtown Chicago for the most part and I never have issues but I do tend to plan the location centrally.

I have a project with the LinkPro Z and range seems limited and reliability is not great - i.e. I have a room with 13 shades and when I trigger a preset that sends all shades open or closed, often some of the shades either don't respond or sometimes don't fully travel... |

Re: Cheap reliable power monitoring.....ya right.
I had to do something similar for a customer that found, during a power outage, that their generator had died and hadn¡¯t been performing its weekly load test.? We just wired the coil of a relay to the generator output and the relay contacts to a digital I/o port on the processor.? Sounds like something similar should work for you.?
