Using EZIO8T for 1Wire + Open/Close Sensor

[Anonymous]

#40572

I have been using the DS18B20 with the EZIOSA & 8T

The temperature is able to be polled & accurately displayed
for about 20 hours.

Then I have to unplug and re-sync both to
get a reading other than 0 or 255.

What software are you using to poll the temp?

When you unplug, is it the module or just the sensor?

What do you mean by re-synch?

Thanks!

I am using Indigo 2

I tried first to unplug then replace the sensor
this did not work

the only operation that did was to pull the power from
the EZIOSA and 8T then re-sync them with the Indigo
software and set them up for one wire temp status.
the readings I would receive were 0 or 255

The rest of the communications for the units seemed to be working
thru out this failure.

Lets try to sort out if it is Indigo or us.

After the 24 hour failure, please try our utility to check the temp:

It appears that it was the polling that would seize the EZIOxx
If I poll for a status every 15 min., after 12 hours it will seize.
If I poll every 30 min., no lockups
I will keep an eye on this
If you disagree let me know and I will continue testing.

We don’t have an issue hitting it much more often that 15 mins, however I am using our sw, not a 3rd party. Keep us appraised and let us know if it acts up again – however if it works for you, I don’t see any reason for you to continue to keep testing. We will be keeping an eye out for similar failures in the future.

I need some simpleton instructions, unfortunately… 🙂 I have an EZIO8T set up in my garage to detect magnetic contact closures for my garage doors and to detect rain gauge activation. I have only been able to get the Input 2 to work. I have the 10k 1/4W resistor and can connect to the 5v wire, but can’t get the EZIO to detect the changes on Input 1 or Input 2. I’ve tried many combinations of placement of the pull up resistor and 5v wire with no success. Can someone help with telling me specifically, where to “wire in” the resistor and where to wire in the 5v wire? I obviously have 2 wires from the contact (black and white) and 3 wires from the cat 5 cable of the connector to the EZIO (green is the 5v wire, green stripe and orange stripe are the wires for the Input 1), etc.

Thanks in advance,

Rick

Rick,
The “pull-up” resistor between the input (I1 or I3) and the +5V. The contact wires: one to the input, and the other to GND. With this setup, the input will see +5V when the contact is open, and 0V when closed.

Eureka, it works. 😀 I hate to feel like such a simpleton…

Thanks!
