HA7Net and HB Weather Devices

[peterd]

I bought a HA7Net 1-wire unit from Embedded Data Systems. It is a web enabled - cat5 connected controller for a 1-wire network. I also bought all the weather devices from Hobby Boards and now i need to integrate them.

1. Is there any weather software out there that will work with this combination of hardware? Everything i have found is for a USB or/and Serial connection - not the cat5/web connection that the HA7Net controller utilizes.
2. Does the HB Wind Instrument include a temperature sensor? I see three addresses and one returns a temp - i guess obviously yes - but i didnt see it documented anywhere and want to confirm.
3. The Temp/Humidity/Solar only returns 2 temperature addresses - no Humidity or Solar in the HA7Net unit - could there be a compatibility issue with them and the HA7 unit? I assumed (ha) by definition all 1-wire components were compatible.
4. Same question w/the Barometer, does it include a tempeature sensor? Again, i see it so i guess so - but I dont see the Barometer address - unfortunately the HA7 only puts out 5volts and the Barometer board needs at least 14 volts so i guess I can get a transformer and wire it up directly to the board - and that might be why i dont see it?

Anyway, lots more questions along this line but my main point is i dont even know what i dont know - if i get some basic direction maybe some of these "integration" quesitons will sort themselves out.

thanks all - pete

I just recently bought a HA7S module to install in a Linux-based WiFi router that I plan to use as a 1-wire server of sorts. I actually used some of the HA7Net documentation to help me figure out what needs to be sent and received. Take a look at this page:

http://talk1wire.com/?q=node/11

As you can see, you can decide what data to send and receive from the 1-wire net allowing you to write/read any device. You will need to know what raw commands and data you are working with, and how to properly parse it.

Below is the output of a C program I've started writing to interface with the HA7S and read temperature data from all DS18B20 modules. The lines starting with "TX:" or "RX:" are for debugging.

If you look at the URL I gave you above, you should be able to figure it out.

Hope this helps.

Pete,

1) I don't know of asny software that supports the HA7Net except some HomeSeer plug-ins.

2) Yes the Wind Instrument does have a temperature sensor in it. It is not very useful though because since it is inside the housing it gets very hot on sunny days.

3) The Humidity/Temp/Solar has 2 1-Wire chips in it. THe DS18S20 temperature sensor and a DS2438Z that handles humidity and solar. The HA7Net won't know anything about the fact that the DS2438Z is being used for humidity and solar. The software you use would deal with that.

4) The Barometer also uses the DS2438Z but doesn't have a separate temp sensor. The DS2438Z does have the ability to report temperature as well though and that might be why it is seeing temp.

Ask away with any other questions and I will try to answer them.

Eric
