Data Storage Capacity

Thanks

I will need the push data for what I want to do.

Thanks

I would highly recommend the Push3 gateway for what you sound like you are wanting to do. It is certainly the most powerful, scalable, stable, and data rich option that we provide. It also allows you to easily create csv files of real-time and summary data. You can use all of our software options. So for what I think you are wanting it will certainly be the best.

My application is monitoring a synchronous pump motor that has maximum efficiency at 3450rpm that corresponds to a frequency of 57.5hz.
The power is provided by a variable frequency drive and the pump curves show preferred operating regions from 2070rpm (34.5hz) to 57.5Hz.
What is the accuracy of your meter's measurements at this frequency range?

Thanks
Jim

Our meters will work from 46-64Hz with the same accuracy (0.5% accurate meter and CT combination.) 34.5Hz is outside of its operating specs. It sounds like you may want to shop for a much more capable, advanced (and expensive) Power Quality Monitor.

Is there any discussion open about privacy and confidentiality concerns w/ stored data?

Is there an option to set a coarser long-term storage summary window, say single-day summaries instead of 15-minute summaries after a certain time threshold, e.g all data older than X days gets chunked into daily summaries?

In the case of residential tenancy submetering it would be beneficial to be able to assure tenants that their short-term electrical usage patterns are not available for later auditing or review. For billing purposes there is never a need to have greater than single-day usage detail. If not already an available feature, please consider adding it to the EKM Push and/or Encompass settings for each meter or account.

Hello John Doe,

When we sell a Push system, it comes with an EKM Push account key. This is a long series of letters and numbers which give you access to the data from that account. If the owner of this key were to share it with anyone, they would also have access to the meter data.

With the Push system, we store the latest 24 hours of real-time data. This by default is once per minute data.

We then take this real-time data and compress it down into 15 minute chunks we call Summary data, which is available via our Summary API. This is how we create 15 minute, 30 minute, hourly, daily, weekly, monthly, and "range" data sets.

We store your summary data in 15 minute chunks for 2 years, then we reduce this to hourly summaries that we store for 4 years, then we reduce this to daily summaries (stored in UTC time) that we store forever. So you will be able to get daily, weekly, and monthly summaries (stored in UTC time) forever. There is no way to customize this per meter or per account.

Here is more information about our Summary APIs: https://documents.ekmmetering.com/api-d ... ary-v2-api

I hope this helps.
