Recent Accomplishments

Started work programming the 1-Wire (TI-MSP430) microcontroller to support DS-2408 8-Channel Input/Output Addressable Switch. This microcontroller from Texas Instrument is one of the most inexpensive and is pre-programmed to support 1-Wire protocol.

Started work programming the 1-Wire (DS-9490R) microcontroller in .NET to support DS-2408 8-Channel Input/Output Addressable Switch . We have basic (straight) digital IO control working in a Windows 10 desktop program.

Started work programming the LabJack U3 microcontroller in .NET. Not supporting 1-Wire at this time but we plan on it. Today we have basic (straight) digital IO control working. LabJack U3 is very popular in the defence industry for monitoring and control (automation) and prototyping weapon systems.

Started work programming the Arduino Uno microcontroller in .NET. Not supporting 1-Wire yet but we plan to. Today we have basic (straight) digital IO control working. Arduino is probably the MOST popular in the industry for monitoring and control training in high-school and college.

2020.04.19 (COVID)
Finished work on the 1-Wire DS28EA00Class for .NET. This is a drop-in class that provides function calls for the DS28EA00. This chip supports temperature and two IO port control.

Finished work on the 1-Wire DS2438Class for .NET. This is a drop-in class that provides function calls for the DS2438.

Moved all web based applications to a new Cloud called Very affordable and supports a plethora of features including SQL Server (database), server logging, mail client (SmarterMail), latest Windows Server versions and much, much more!

Created "Console Template" supporting 1-Wire for Windows Server. This is a boiler plate (starter) for creating Console Applications and includes logging, data access, error logging and configuration management (.config file). Console applications can be launched from Windows Task Scheduler.

Created "Service Template" supporting 1-Wire for Windows Server. This is a boiler plate (starter) for creating Windows Services and includes logging, a timmed event, data access, error logging and configuration management (.config file)

Added "Delta-T" calculations to web/phone temperature site. Delta-T allows the 1WireHome system to determine HVAC efficiency. This can (future) automatically determine problems with HVAC system. This includes monitoring HVAC amerage pull (AC) in real time.

Changed promotional site to show important data first, promotional informational second.

Upgraded web and smart device so it supports more devices. New devices include tablets and other dis-connected devices. This includes "web services".

Increased Cloud bandwidth by a magnitude to support expected traffic growth over the next few years. New bandwidth capabilites should allow 10,000 accounts. Unexpected near-term growth can be addressed with additional web servers and multiple database instances.

1WireBits launched the web site allowing you to monitor and control your home on your smart phone or desktop. The link is the current early beta version 0.4 which shows temperature from sensors around a real installation/location (live data!).

2015.08.17 has started testing Windows 2016 Server to support our future cloud environments. Windows Server 2016 is a significant Microsoft release with a new IIS version capabilities, Microsoft managing Virus Protection (instead of Symantec Anti-Virus) and superior server port management for enhanced security.

The 1WireTemperatureService is complete. This Windows Service records temperatures to your local computer database, the Cloud or both. Features include adding new 1-Wire ROMCodes automatically, storing hourly temperatures and removing normal-periodic readings after 90 days.

We have successfully stored data to the cloud for users. This is a significant achievement since this now allows us to write smart phone applications for users. The possibilities are endless! We are very excited about this at!

We are now running on our new servers in Dallas, Texas. Basically we have our own cloud established for storing data. This is one of many steps to get into the home energy management mainstream.

Working on missing progress data betweem 2010 and 2015.

First system built that supported sprinkler system management by outside temperature. All running on a Windows home desktop computer. All using 1-Wire technology.

Started working on the DS-2408 and DS-2450 board interfaces based on the knowledge of working with the DS-18S20. There are many basics to the 1-Wire .NET programming for 1-Wire devices.

Designed and produced our first board supporting the DS-18S20 temperature chip. Unfortunately this board design made 1-Wire networking unreliable. We gained tremendous knowledge though on the Microsoft .NET programming side. We are using the USBMicro U421 microcontroller connected to Windows via USB.



We are different! We intend to be. We want to build the most configuration and software advanced 1-Wire boards available today using all current software interfaces for 1-Wire and web technologies for home computer and smart-phone support. This includes total home automation.
