1wire support

[Techstyle]

I have the same device, good luck.

Damn! If only I'd held out a little longer, you'd be floundering and I'd be watching.

Forgot to mention that I've set this up on a 1004 test rig (not my installed 0810 system).

My system is all in pieces at the moment, I have no idea where the device is

[Techstyle]

I found it plugged it in (0810) without the sensor and added device template #2161, waited for a bit then got this:

in an earlier message Hari said the error: 22 was a error because is no sensor.  Plugged in the sensor and get nothing.

I added a multilevel sensor as a child but I am stuck on what the port address of the sensor is

I plugged my adapter into my working 0810 installation and got the same result. Looks like things are trying to work - apparently the device is recognized and assigned to a USB port. The 1-wire software appears to attempt a handshake but can't quite get there. So maybe there is hope for us. I had just about resigned myself to finding a new rs232 adapter.

Hi Guys,

You only need to had the 1-wire interface in the webmin. Choose the port its connected.
You have prewired sensors?
No need to add the childs manually. Mine showed up in the webmin after a couple of reboots.

Here are a few pictures. The adapter plugs into the USB port, then a phone cable with sensors plugs into the adapter. I only have one temp sensor on a short pigtail right now, but the house is wired for temp sensing in almost every room. My plan is to use this info to make decisions for the HVAC system.

One of the problems is that the template won't allow me to select the ttyUSB port the adapter is connected to. It only allows me to select ttyS0-3 (rs232 ports).

The screenshots from the 0810 or your 1004 testrig?
I couldn't get mine to work on 0810. But managed to get it installed on 1004.

You'll have better luck allowing Hari to ssh into your box to see if he maybe can fix it.

The shot is my 0810 installation, but it appears to be the exact same template in 1004.

twodogs,

the template should show you all available serial ports, including USB serial ports.

[hari]

yes, it should show ttyUSB, too. Maybe run UpdateAvailableSerialPorts.sh and see if it shows up in the list..

[Techstyle]

In Webadmin mine also showed the same, serial ports only.  However it still seemed to find the device as the log said:

Code Select Expand

Can confirm the correct procedure in 0810, do we need to add the child (as stated on the Wiki) or do we wait until it is discovered?

this raises another point the device will try to look for the sensor 50 times and then it will stop trying, how do you restart it again?

[twodogs]

No luck here either. I rebooted the system. I expected a "some devices failed to load" error but did not get one. I saw the 1-wire device load during the start sequence. So I had some hope, but the template still only has serial ports showing (like in the picture above). I tried

Code Select Expand

cd usr/pluto/bin
sh UpdateAvailableSerialPorts.sh 

It appeared to run without error but the template still showed only rs232 ports. My 1-wire log shows the exact same error 22 that Techstyle reported in post 153. Plugging or unplugging the temp sensor to the adapter has no effect - still get error 22.

[twodogs]

By the way, thanks Hari for your help. I know you might have other fish to fry. On the one hand, the 9490R seems like it might be a good piece of hardware for LMCE to support - if you agree I'll do whatever I can to help get the thing to work. On the other hand if this seems a waste of time, I'll just buy a different adapter.

twodogs, I didn't see your pics earlier but I think we have the same thing in mind:


I have also wired my house and plan on using some of my CAT5e drops to share 1-wire and POTS over.  I have wired to each room, outside in a screened porch, outside proper and in the pool 

I had not tried to use it in windows yet but I thought I should incase my wiring is suspect:


apparently it is getting cooler in here.  this windows tool does give me the serial number of the sensor as '210008002F424310' is this what LMCE is expecting as port?
