With a big thanks to FlyingDomotic , and for future reference: this is my payload from a Growatt inverter (Growatt mqtt messages produced by Grottserver) and contents of MqttMapper.json (including messages from my Itho ventialtion unit: I set the 243-29 device (electric + counter) to 'calculated' in ...

A tip for others who run into this problem: if you delete a device which was created automatically by MqqtMapper and expect MqttMapper to recreate it for you, that won't happen: an error wil be logged in Domoticz every time MqttMapper tries to run. Restart Domoticz after deleting a device created by ...

Thank you very much! I came to conclusien pv1voltage being on a sublevel of values while you were writing your reply! It's so obvious once one understands And thanks for the extra examples!

I am struggling to understand the mqtt syntax and could really use some help. The examples at the mqttmapper github page lack some real payload examples for me to understand how to map the mqtt payload to domotiz devices. This is the payload of the grottserver which spits out information about my ...

Thanks! Was just about to come to the same conclusion Just getting acquainted with mqtt:-)

I can't get mqqt autodiscovery to work. I have GROTT Server running in docker to catch the traffic from my Growatt server to server.growatt.com, thats al working properly. I have Eclipse-Mosquitto running in a docker container, and the messages from the grott server are received (see screenshot of ...

SOLVED, replace /json.htm?type=command&param=getdevices&plan="+$.roomplan+"&jsoncallback=? with /json.htm?type=devices&plan="+$.roomplan in the html code After upgrading from the november 2022 to the february 2024 version, none of the values are retrieved anymore. I tried enabling 'allow plain text ...

Smart meters report T1 and T2 (accumulated) values with each data output, so Domoticz will simply apply the T1 and T2 prices to each value

power usage isn't measureable per phase in a 3 phase system. The power usage is formed by the 3 phases combined, because the sine waves of each phase is 120 degrees shifted from the other phases.

Did you ever find a solution for this? This is driving me insane. I'm trying to build a script to put charged current from a solar panel array into one meter and consumption from the batteries into another one. But using dZvent and updateCounter() fails and I never get the sum for the the day, just ...

But how do I do this filtering of negative values to one meter and positive to another? The function updateCounter() doesn't work with incremental counters. Please see this thread. Any suggestions? https://www.domoticz.com/forum/viewtopic.php?f=59&t=19098&p=184974#p184974 You will have to program ...

I too have this problem. I'm trying to meassure current in/out (solar panels in a 12v system) to get the netto for each day. Seems like the calculations on the overview are correct with pos/neg values but the graphs go haywire when I feed them with negative values. A negative valuye will equal a ...

This works fine, but since I have a 3-fase installation, it's possible to consume power from the supply and at the same time deliver back. That seems impossible to me, and irrelevant to wether you have a 1-phase of 3-phase installation. I have a 3-fase installation with smart meter and solar panels ...

a simple 'cat /dev/ttyUSB1' will tell if any data is received. Issuing this command from the command prompt should produce readable output every 5 seconds or so.

I have a Remeha Calenta heater with an iSense thermostat, the iSense talks Opentherm. The OTGW is placed in between the thermostat and the heater, and acts as a passthrough device between thermostat and heater. Domoticz reads all relevant values (water temp, room temp etc) by querying the OTGW ...

It has been quite a while since i have been thinkering with this. I'm using a similar approach to vromas for a few years now: the growatt stick is sending the data to my Synology NAS. My Sunology passes the traffic trough to the Growatt servers, but its also captures traffic to data files, which are ...

Nice

I grab part of that website to show on my frontpage:

Nice. Not only the Algrabridge, but when garbage is collected. Could you please share the code for that? My code is still a bit messy, so here is the whole lot. look for "afval" in the code to find the relevant bits for the garbage info. <!DOCTYPE html> <html lang="en"> <head> <style type "text/css ...

i am unable to get my.domoticz.com running. The green icon shows up okay, but clicking on it gets me "This XML file does not appear to have any style information associated with it. The document tree is shown below." and then it returns to the green icon. i have deleted the instance, and now the ...

Just thought i'd share my frontpage. The information about the next garbage pickup is grabbed from the (dutch) afvalwijzer.nl site. And i think switches which state On or Off in big letter are not informative enough. So i swap the vdata and desc element, and make the button text yellow when on and ...
