Data logging Widget

[eman5oh]

I am loving the data logging widget, it allows me to have all my channel logs on one one webpage and no need to login.  The only thing I notice is my time offset is not applied to the widget but is applied to the data logging on the iobridge dashboard. Is there a way set the time offset for the widgets that i am missing? I also was wondering what the voltage rating is for your relay board? Thanks

i cant help you with the widget question, the relay however i can:

The maximum voltage/current for the relay are:

no more than a 5 amp draw.
or
no more than 60watts.

Whichever is lower.

Watts are calculated using: (amps) * (voltage) = (watts)

what are you trying to do?

Hi,

Another issue with showing the time of a reading is that, when using "auto refresh on" and "live chart"  style for analog input in the widget setup, the time displayed when moving the mouse over the chart is neither GMT nor my offset time.  I assume it is the local time at the IObridge server, possibly Florida.  Is there any way of changing this?

Thanks

I am looking to switch a 1/40 hp circulation pump on and off it should be around 20 or so watts factoring in efficacy but is 120vac so that is why I ask about the voltage. I am also looking to operate a 24 vac zone valve as well, I don't have that yet so I am not sure on the current draw. This is for heat dump on a solar hot water system. I was thinking of ordering a couple of the relay boards and putting them in a separate box to avoid having 120 on the exposed pins of the relay board and running wires to it. I may just wire up a set small 5volt relays that I have laying around. I see from the pics that the boards have a suppression diode and a resistor on them, dose any one know why the resistor is used?

The live widget was on "Florida" time - it's going back to GMT in the next round of updates. We are working on the timezones for the whole system. Soon you will be able to set it on your profile and the offset will propagate to widgets, actions, APIs. It's not the offset that is an issue, it's day light savings.

Also, how do you feel about the "title" being in the widget. Right now the data log widgets have the title displayed in the widget. It's redundant for the dashboard and it would be easy to add if you added it to a webpage of your own. I am thinking about taking it out.

Right now I use the title feature in my own page, but like you say it easy to add the text to my html. I have not tried as of yet but can I make more than one data log widget for the same channel? I would like to make up few for each channel  showing the last day week and month.

im not sure about the circuitry...

at 120v, at most, you can switch 500ma. pumps and motors tend to have a higher current draw, so i would be careful with that. plug the pump in and use a multimeter to check the amp draw... also, if the pump becomes clogged or such, it will pull more amps.

for the 24v system, it has a max limit of 2.5 amps. You probably would be ok with this, again ,depending on the valve.


If you were going to assemble your own relays, you can hook the circuit into the digital out and ground pins to switch a 5v relay.

If you were going to assemble your own relays, you can hook the circuit into the digital out and ground pins to switch a 5v relay.

Although the digital abouts are only rated at 20mA, and I believe most relay coils will draw more current than this, so be sure to use an NPN transistor between the digital output and the relay to prevent burning at the digital output.

good catch.  it depends on the relay, but most will need that
