Topic: Brultech / Power and Energy Streams

Hi,  

Samotage: Thanks for all your hard work on this over the years.  I totally understand your need to make some money on this somehow.  I have noticed that I have two streams for every item:  

Power Stream: kW   - I think this is the measurement right now.

Energy Stream:  kWh  - I think this is the measurement since the last update

Is my description correct?

Do I really need both of these?  (sorry for my lack of knoweldge)  It would seem the kWh would be more useful, but I absolutly could be wrong.  

Can I drop one of them?  If so which one should I drop?

(I did change my update interval to 120.)

I have a Brultech GEM.

Thanks,

Topic: SEGmeter / Configuring Data Rates to work with the new pricing plans ?

An update on data rates, the rate used for calculations is now being determined over a 3 day window.  This will stretch out in time from now.

You can view what this will work out by looking at your account page.

Sam, @samotage

still thinking about data retention.

Topic: The Open Grid / Calculations not working (all 0's)

It seems like some streams got stuck when the server was rebooted yesterday to fix a memory issue, that was casing problems.

They have been cleared, and all should be good now.

Topic: The Open Grid / Calculations not working (all 0's)

I'm seeing the same thing but only on my energy (kwh) based mesaurements, not on the power (w) based ones.  And only on one of my two devices.  Any ideas?

 

Thanks

Ben

Yeah, for me just keeping 30 days of power would be great and aggregated energy after 30 days.

One way to do this, and it depends on the application, is to keep the raw data at e.g. a frequency of one minute for a short period like a month, then to keep 5 minute data for three months and 30 minute data for 12 months. 

The aggregation tools can be setup with layers to do it like this but it also puts a cap on the total amount of data being stored.

Then the user can look at monthly figures over a one year period for a long term view and look at finer detail when necessary for the recent data.

Hi Sam

Raw data,  I'll cast a vote in for 1 month.

Aggregated / Summarised can I stretch the friendship and say forever ?

This would would work well for how I use energy data (kWh). 

Power data I'm less certain. Possible I could do without data older than 30 days at all.

temperature data, pref is forever at 30 min windows.

Thanks @kkemp

My thoughts are:

1. An option to keep the amount of raw data

2. Another option to keep the amount of aggregated/summarised data.

Summarised data will of course be cheaper, as it has much less storage overhead.

I would be interested to see what people think are a fair and reasonable time frame for raw and aggregated data would be.

I think you are looking at this feature completely wrong. This feature allows you to keep historic data vs just deleting it after 2 years. If you only keep 2 years I'll have to move to a system that can keep my historic data. If instead you charge per data point stored then eventually it'll cost too much and I'll move to a different system. Or if you do what you are doing now a new customer and a customer with 5 years of data cost you the same amount. So this feature improves your profit margins or allows you to charge less and retain more customers.

I have looked at rrdtool - and many others, and it sucks.  Period.

SEG could not do what it does if that was the underlying architecture!

My understanding is that you can run the analytics and graphics on the rrdtool data. The rrdtool is interposed between the incoing data and the analytics. Just a suggestion, but there may well be better tools or techniques.

@Dargs you got it right for some of the older v1 SEGmeters!

@robb01 lols rrdtool... Perhaps the ugliest most useless tool for data storage IMHO... Can't run analytics on it and it's file based - I think the '90's just called and wants it's rrdtool back!  

@kkemp I think this could make sense, having a setting that allows people to select the raw and aggregate retention.  I'm not going to be deleting any data until I have this nailed.  FWIW - I have to go to some effort to implement this feature which will in effect reduce potential income... Do work to get paid less!  Must be a concept from some parallel universe.

kkemp said: Hopefully instead of deleting data you  spend time creating a feature that allows one to set retention periods and roll ups so they can keep their history but at more realistic intervals such as daily or even hourly. 

Hey Sam. Have you considered using rrdtool to achieve something like this? Its uses a data consolidation feature to set how much data is stored for different periods of time and thus limits the total amount of data stored.  Could be useful as a means of controlling the cost of storage. Maybe this could be a feature option depending on what pricing option the user wants to go for. I.e. limited data storage or unlimited.

Ah it seems its as easy as changing the Cycles, got it set to 60 now, and the data is sending through at about every 45 seconds.

Hey Sam, 

I'm happy to go to paid, been a good 4 years of not having to! 

I'm still running v0.18 on my segmeter v1, just trying see whats the best way to get the dataz sending above 40sec,  is it around here somewhere that I should add more averaging & cycles? 

 

 #define CHANNELS 3 // Current sensor(s) #define SAMPLES 1000 // 1000 Samples to take

#define AVERAGES 3 // 3 Number of RMS values to average

#define CYCLES 2 // 20 Number of times to cycle through the calculations

 

Thanks

dargs

Topic: Comments and Suggestions / Integration with Amazon Web Services (AWS) Internet of Things (IOT)

An interesting point on the Amazong IoT platform...

$5 per month per million messages.

Consider a 100 stream SEG setup, sending data every 10 seconds.  Assiming that each data point is a "message" in Amazon speak that is:

10 seconds, gives 6 messages per minute, 360 per hour, 8640 per day. 

At 100 streams, 864,000 messages per day.

26,784,000 messages per month, ~$115 per month - with no visualisation, analytics or any of the other magic in SEG to make sense of it, and who knows what work is required to set it all up?

Just some random thoughts,

Sam, @samotage

SEG has been doing stuff like this for ages, and is the whole Control application - which has been in alpha for some time now.

It's a great feature that allows inputs from devices and other things to run through decision trees and issue commands back to the device to do things like turn stuff on or off, adjust set points and a host of other things.

It's been tricky to make work robustly, but it's there and has been baked in from the start.

This is something on the roadmap after the paid service transition has completed.

At the Amazon Summit the other week they annouced their Internet of Things Services that look at the capturing of data from devices, processing of that data against rules, capture and storage, and the triggering of actions back to devices.

It would be interesting to see if customers could take a larger responsibility for thier own footprint using SEGMeter technologies that integration with these services.

Ah, excellent. The pricing grid should make this distinction clear as that's a huuuuge difference.

@sandeen, I don't think Spotify is a comparative model... they a unicorn have massive funding to do this kind of malarkey... and probably running a negative gross margin (see my earlier post) - plus it's well documented that the actual artists get SFA from these services.

People can live without Spotify - there are many other slippery options...
