I did have the same type of problem. Because I started collecting data from Enphase right after the installation, the begin value of the Counter in Meter_Calendar starts at 1 (made it so). I made the data in Value and Counter consistent, so the counter is value+previous-counter. The last counter (of ...

Would stopping Domoticz, change these values in the database with sqlite3, and restarting Domoticz work? Preferred way is: stop Domoticz, backup database, do changes with sqlite3 and restart Domoticz. In case of problem: stop Domoticz, restore database (copy database backup over corrupted/not ...

It is not advised to update the meter table directly, for example by sqlite3. If you want to update a counter to a corrected value it is better to use the domoticz.devices().updateCounter() function in a small separate dzVents script. In that way you make sure the value is updated in the meter ...

I have wrong values in table meter in the second column (=total Wh produced). All these values need to be subtracted by a certain value. When I change this value in the right value at the last date/time-value I would expect that the measured Wh in the current 5 minutes would be added to this value ...

Thanks that did solve my problem.

I have normal values in august this year for a set of PV panels. However when I look at the graph for the months there is a very high value for that month. I looked in domoticz.db and can't find the table where such a value is stored. I would expect this value calculated from the meters_calendar ...

The hack with the file to store the previous counter value is not needed.
Devices[unitID].sValue contains the previous stored sValue, which contains two numbers: Watt and counter.
So Devices[unitID].sValue.split(';')[1] gives you the previous value of the total Wh used/produced.

I managed to change the code so used/produced energy is accounted for. Could not get previous counter values from the database, but I use a file for each device to keep track of the counter value. I have no idea how to upload the new source.

Please IGNORE. See Python for further discussion.

Just found out that in the line: one needs to replace the zero in ";0" by the value of the used/produced energy in Wh.
Will develop the necessary python code to show the use/production during the day.

I have a combined bash script and pearl script to get the values from the smile and calculate 5 minutes W averages. The smile has about each 8 seconds a new value for used and produced Watt. So averaging this during 5 minutes and multiplying this by 5/60=1/12 gives the produced/consumed Wh. One can ...

I installed the plugin Plugwise Stretch and got it up and running. When I look at the widget on the Dashboard or Others, it shows the Watts when there is use or production. I my case mostly production. My Stealth is in the circuit of my solarpanels. However I also see Today, but the value is always ...

I use this plugin on an openSUSE Leap 15.2 Raspberry Pi 4B system and had the same type of error messages. The reason was that domoticz runs as user domotics and group domoticz. I assume that is the same on Synology. Changing file protection on domoticz files to be owned by root does not change the ...
