Does V1 of the Home Energy meter report battery status? If so, how can I get the status of the battery? I am powering it with the USB power adapter, with battery as a backup, but it would be nice to know the battery level.
I appreciated the GroveStreams recommendation. I finally got my Aeon HEM v1 connected up and immediately set out to send the data to GroveStreams. I spent several hours tweaking my dashboards to get them just how I wanted them and was loving the data I got.
I was wondering in the back of my head how much of the 5 MB/month I was using of my free account at the default polling rate but didn’t dig too far into the interface to find it. Well, I woke up this morning to a message on my dashboard that I had gone over the data limits and no more API calls would be accepted. I found my usage numbers and realized that I had sent about 15MB in about 16 hours! Needless to say, without some major increase in the reporting intervals, there’s no way to use GroveStreams in the free or $5/month tiers.
I’m looking at Splunk on my own server (500MB/day for free) or maybe Initial State’s first paid tier (with unlimited data and streams but limited support) now.
Can you share how much data you send to GroveStreams and how you tweaked your reporting to fit in their fairly low limits? I enjoyed the interface and the QuickStart that you posted was very easy to get up and running but I feel that the other options out there will let me work with the data that I’m able to collect.
EDIT - I just realized that you developed the Device Handler I’m using as well. Great work all around and really appreciated!
I am having trouble with my Aeon Labs Home Energy Monitor. I can’t get your app to work. It installs fine, but I get no results on the screen. See my screen shots below. Any help would be appreciated.
I figured it out - it was only working on battery and so it wouldn’t report anything. Now, I plugged it into an outlet and it is working fine, but I only get the first two rows to show anything. The other rows aren’t showing results. Any thoughts?
I have finally got ST to ship data off to Splunk. Just follow the directions in the post and you should be good to go.
I haven’t implemented the LAN side of things yet plan to work on that soon. I want to set it up so you can select LAN/Cloud and have it construct it that way in case someone is using the Splunk Cloud stuff. Let me know if you have any questions.
Anyone know whether this meter can differentiate between import and export? (Most can’t).
Don’t know whether it’s the same elsewhere, but here in the UK many of us have microgeneration (PV panels - yes, we have sunshine sometimes, wind turbines, etc.) and any excess is exported to the grid via the normal connection. Our meters are designed so that they don’t run backwards!
Trouble is, most simple ‘whole house’ meters can’t differentiate between, say, 4kw import from the grid, or 4kw export.
Even if it can, it for sure doesn’t store import/export KwH in seperated sets… likely you’re not selling your power back to the grid at the same rates the power company charges you, so it wouldn’t be possible to calculate the difference given the unit only has one KwH store variable (import)
Since it might be possible to show a negative Kw usage, someone might be able to cook up a tool to do the KwH -/+ calculation on the hub or a computer, though this would be inaccurate as far as the hub missing packets or due to rounding errors. They only KwH value you can only go by is the HEM’s KwH variable that’s calculated on the HEM itself.
I’m willing to bet as solar gets more popular, we’ll see new generations of HEM monitors that have two data stores for KwH import/export. Hopefully we see that soon!
I wasn’t actually thinking about cost. For me it’s all about device switching. I have a number of low priority electrical appliances that I only want to switch on when I’m exporting sufficient power to run them for free.
