yes but not for those you want. If I get a chance I implement the change I suggested, but don't have much in terms of cycles so can't give a time.

It gets difficult if you don't feel comfortable changing the modus C++ code on the arduino side. The code is easy to follow and change.

There are several options presented in thread. If you don't feel comfortable with the C++ or looking at the Mango code, as stated earlier you ca create an event to write to each of the registers in your arduiono with a UNIX epoch timestamp from Mango.

That is the one I used and modified on my own for my own consumption last year. Even if you add a broadcast in the arduino code, the UI on the Mango side won't let you add a broadcast address of 0. So elegant changes or a hacks needs to be made, hence my suggestions.

You can't set the broadcast address of 0 on the mango UI. If you want to work with the existing code base, select another address say 1 as the "broadcast" address. Not sure what you have for modbus implementation on the arduino side but probably is minimalist and probably does not have broadcast handling capabilities. I am assuming you got what was floating around for free. I had to add modbus functions on the arduino side to do what I want. I did not do broadcast functionality but it should not be too hard to implement.

I would change the code to handle a "broadcast" address and have only one device respond to a request to the master and the others are passive listeners. That way only one entry is required on the Mango side along with a CRON event to trigger write the timestamp.

Otherwise you could probably use Mango events to fire off to write the date/time as a unix epoch timestamp or what ever format you want to send to registers in Modbus and manually configure a date/time point for each device. That would emulate a broadcast.

Not sure if that helps.

Well that would explain the spikes.

I have simple feature request..Deadband option like that presented in the datalogger.

What is send period of 15 minutes do? It was not described in the help for this.

I set up 1 feed with 9 data stream as a pachube publisher. I have the update event set to on change and snapshot send period of 15 minutes. I am not understanding why I get API rate increases every now and then. What in the configuration is causing such a high API request rate? Am I correct in assuming the the way I configured it should send changes to Pachube every 15 minutes? Or is every change in the point causing a pachube publish event regardless of the send period?

API request rates
You were last rate-limited less than a minute ago (on Fri Oct 15 04:36:04 +0000 2010).

Requests using your API key were denied because you exceeded Pachube's rate limit policy.

Here are your API request counters for the last 3 minutes:

* 2010-10-15-04:36 --> 12
* 2010-10-15-04:35 --> 29
* 2010-10-15-04:34 --> 29

Ok. My bad. I always sand-boxed myself in the data source world. I never used publisher and saw it. No brainer now.

Well I added the point link back since I thought I saw it work without it. I can only make the push to pachube via the point links.

I removed all point links. Now when I go back to point links the target point only has two entries in the drop down. I have a lot more than that as per the source point. Any idea why the drop down is populated with only two points?

That did it. Left overs from something.

thx

System setting = 1.9

Pachube manual feed via put. I tried it without a point link. Works fine.

Thanks

So in the name field of the panchube point detail, I enter the modbus tag name?
