I have made changes before to a P1 device's data in the database with a sqlite command or sqlite express and there is no issue doing that as long as you know what you are doing. just stop domoticz, make an backup and update the data. I figured out that the fields contain by looking at the ...

I have an electric car which I can charge at home. To measure the used kWh, I have a kWh meter and an esp8266 wifi board which counts pulses from the kWh meter. The pulses are then sent to Domoticz, which is running on a raspberry pi. This works great! But while using this setup, I have made several ...

You can use the P1 meter for this but then you have your ESP do the counting as this meter uses a total counter (like the counter on the kWh Meters). So you have to find a way to have the ESP remember the total count. One way is to first get the current total count from Domoticz by http API call ...

Well, even I don't have the kWh meter module yet, the test setup does work and counts every pulse I (manually) generate. Right now I have used the Virtual Sensor "Counter Incremental". Is it possible to make the high and low rates visible (lower rate during nighttime and in the weekends, high rate ...

Something similar like this maybe? https://www.reddit.com/r/arduino/comments/6y6jzs/esp8266_web_requests_from_external_interrupt_not/ ah I see you found out the same :) Thank you! That is indeed something similar. For testing I am using a push button, because I still need to buy the kWh meter ...

Okay, I have discovered that it might not be a good idea to do the http reqest within the interrupt handler. I now do only count in this handler and check in the loop if there has been interrupts counted and than I will send the command to Domoticz. That seems to work now, I only discover it ...

Not totally sure I understand the reply about the other line, but you didn't answer my question about using Userid&Password to access domoticz. ;) Sorry, I was not reacting on your post and my reacting wass also not very clear, as I am reading it back! Sorry! :-) What I ment was, that I took ...

Well, I have added the one line to my other code where I send the temperature to Domoticz and there it works, so I will check the differences!

remove the semicolon at the end of the svalue

Just double checked, but removing the semicolon did not work.

Just a quick thought that might solve the issue remove the semicolon at the end of the svalue sendDomoticz("/json.htm?type=command&param=udevice&idx=31&nvalue=0&svalue=1"); if that does not work, try the command in your browser first (adding http://yourip:port in front of it) Hi, thank you for your ...

I would like to count the pulses of a kWh meter. I have made a test with a button (instead of the kWh meter) to test the code first. I have made a virtual device and added a coutner to Domoticz. If I enter this line in my webbrowser: http://192.168.2.127:8080/json.htm?type=command&param=udevice&idx ...

I did find the solution and added a task with next command: cp -avr /volume1/@appstore/domoticz/var/backups/ /volume1/Bestanden/Komputer_en_mobiel/Domoticz/Backup Now every day a backup will be made from the complete Domoticz Backup folder (check the automated backup option in Domoticz settings) I ...

Install the synology package from jadahl and plug in the usb p1 cable in the synology. How to set up the p1 meter in domoticz, you can read all about it at my blog! https://www.twoenter.nl/blog/domotica/slimme-meter-uitlezen-met-domoticz/ I did manage to get it working, thanks to your blog! Thank ...

Thank you both; I should have used the help a bit more, sorry for that!

Dutch language won't be a problem, because I am Dutch myself!
I will read your blog!

I have read that it is possible to install Domoticz on a Synology nas. But is it somehow possible than to read the values of the energy meter? Yes that's possible if your Synology NAS does also have a free USB port. Thank you for your quick reply! That would be great! I have two USB ports, one is ...

I run Domoticz on a rapsberry pi, to monitor my energy and gas usage. Unfortunately, the raspberry is sensitive for interuptions in power and so on, so I had to re-install it several times and am missing several measurements from those days. I have read that it is possible to install Domoticz on a ...

I have added some line in a srtupfile and now it works perfectly!
Add these lines:

SOLVED!
Solved by adding those two lines to:
/etc/rc.local

Domoticz survives a reboot now!

Tnx for the help.

Thank you for your reply. I am almost there. In the thread you mentioned, these lines helped: sudo systemctl stop [email protected] sudo systemctl disable [email protected] But after reboot I need to run them again. But I also have to change baudrate to the wrong number and ...
