The screenshot of mini-grap-card, I have posted, has daily usage not weekly.
I think it doesn’t make sense to display data for longer periods than 7 days (but TBH I haven’t even tried).
The problem here is that your mini-graph-card will need to fetch all the data for that period (every single value change) so it can be a lot of data. Mini-graph-card has some browser caching mechanism but if you login on the new browser / incognito-window / different device it will take some time to download everything from HA.
Downloading a lot of data is not the only problem. AFAIR (when I have done some changes in mini-graph-card) it caches the actual data - not the aggregates. This means on every page render it has to process all of the data. I guess it can kill/freeze your browser on slower devices.
The only reasonable option to show data for longer periods in HA is Grafana. It is processing and aggregating data server-side (in DB engine). But of course it has downsides as well (mentioned above).
In terms of the utility meter tariffs config - it doesn’t matter. On the end such configuration produces two separate sensors - each for every tariff. You can display them on separate cards or combine them in one as mini-graph-card is able to display multiple plots on single card.
Ok. Thxs for those explication.
I can see that it can freeze your browser. I understand the point.
I’d like to have a dashboard of my energy consumption for weeks and month.
I’ll try grafana with it’s own DB, you’re right.
I just came across the utility meter and reading the integration page I got a couple of questions. I have a E3DC photovoltaik solar power converter including a battery. From it I read current sensor data via a modbus integration. These read outs are provided in Watt [W]. One read out is the sensor.e3dc_power_consumption giving me the current power consuption in Watt [W]. Another one is sensor.e3dc_grid_power, which is also in Watt [W], but depending if power is moved into the grid (overproduction of the PV) or bought from the grid, the value may be positive, or negative.
How can I now track energy consumption [Wh] using a utility meter?
I would like to track one the energy consumption of the house and the energy consumption from grid (positive values only).
This thread is not for answering random questions about utility meter and related things. Please create a separate one for that kind of stuff.
Short answer for your question: it is not a good idea to compute Wh from W as this won’t be accurate for sure. Seek for help via new thread or find a more relevant one
Hello @dgomes, I found this conversation when was looking for utility meter report. After reading your message I started to think - why changes in the UI are necessary for the first iteration? Why the array is necessary? Looking back at my utility invoices and reporting ability of other IoT platforms, here is how I see the change request.
To me it looks like 2 small changes will greatly improve reporting ability of the Utility Meter component. Performance problems are also considered with this RFC.
First of all many thanks for this writeup! I feel little bit guilty that I have left this thread without traction and I’m very glad to see that kind of post here (proposal how to tackle the problem).
Let me just understand your suggestion. If I understand correctly you propose that utility-meter will expose sensor (e.g. sensor.pump_monthly_report) and recorder should be disabled for it. To store the data it should make a direct DB call. Is this what you are proposing?
If that is the case I see few potential issues:
Currently utility-meter is a regular sensor. It is just producing some values (it’s state) based on other sensor states. It doesn’t interacts with DB directly.
I’m not sure if direct access to DB is allowed
Recorder stores all it’s records in the tables which have a general purge settings so I guess we won’t be able to store such data in the regular tables
HA core team is doing table structure changes from time to time
So we will need to maitain special table in the DB, I assume we don’t want to have there any retention policy
I am also looking for a way of creating daily, monthly, annual reports/graphs for my energy meter readings, I am using separate meters for general consumption of the house, heat pump and car charger.
I very briefly looked into the statistics card but it wasn’t obvious to me, how to use it for creating reports. Any pointers gladly taken! Thanks!
