Så kom jeg lidt videre. Har nu fået en temperatur ind under parameters, og på den grafiske forside. Der er dog endnu et problem

Temperaturen svinger op og ned mellem 30-70 grader med få sekunders mellemrum. Og den ligger og på skrivebordet med konstant 24 grader

Er der støj fra 220 v ledning i nærheden? Er ledningerne til temp. følere skærmet?

Det kan jeg ikke garantere jo, men har et andet program hvor temperaturen bliver vist korrekt, så vil mene det er noget software der er problemet.

Der er ingen skærm i kablet..

Appreciate the initiative very much. I plan to implement a better control system when I get time.
Is there any module that will make it easy to to add solar collector control and motor valves?

Hej Kim
Svært at gætte hvad problem er. Men det kan f.eks være at dit andet program har et SW filter indbygget som beregner gennemsnit over mange målinger, imens PellMon måske ikke har et SW filter men istedet forventer at HW er støjfri.
Hvis du har en lille kondensator på f.eks 100nF- 1uF så prøv at forbinde den parrallel over føler

Pso, there is no module for solar control, but it would be nice to have one... If you use a raspberry pi you have full access to all gpio pins as inputs or outputs so you can control pump motors with that. The alarm plugin can be used for simple control and the calculate plugin for more advanced scripting, but it might be best to make a new plugin for solar control.

Kim, the varying temperature sensor readings are from the simulated fake temperature sensor the owserver provides to test with if you don't have a real sensor connected. Either you have not found your real sensor (wrong path) or the owserve does not have access to it at all. You need to configure owserver correctly for the onewire bus master you are using in /etc/owfs.conf

Det er desværre alt for avanceret for mig at få igang, så jeg har droppet det og bruger en mere simpel løsning

As I understood it you had all the hard parts working already, it's just that PellMon does not (yet) make it possible to read a DS1820 temperature sensor connected like they do in that project: http://www.projects.privateeyepi.com/_/ ... ircuit.jpg This is the cheapest way to connect a DS1820, but it's hardly the simplest and also unreliable with longer cables or many sensors.

PellMon instead connects to a runnig 'owserver' from the OWFS project , which is a separate program not made by me that supports most everything under the sun regarding onewire stuff.

The simplest (but not cheapest) way to connect onewire sensors to an owserver is to buy a usb-adapter: https://www.m.nu/adapter-1wire-ds9490r-p-49.html
Some ready made sensors: https://www.m.nu/temperatursensor-kabel ... -p-44.html
Some ready made cables: https://www.m.nu/forlangningskabel-p-37.html
And some splitters: https://www.m.nu/forgreningskontakt-rj12-p-33.html

Then you just plug everything together, install the owserver with 'apt-get install owserver' and it's up and running.

I might do a PellMon plugin for reading onewire sensors connected directly to a raspberry GPIO someday, it's really quite trivial, but for anything but really small systems with short cables and a couple of sensors a real hardware busmaster (usb or I2C) is really worth the money in my opinion.

Version 0.5.0 has a new plugin Onewire made for reading onewire temperature sensors using the kernel driver (like it's done in the privateeyepi project), instead of connecting to an owserver that takes care of the onewire hardware. This plugin only supports reading from temperature sensors supported by the w1-therm family driver, where the other onewire plugin OWFS supports mostly any kind of onewire hardware.

The reason to use 'Onewire' instead of 'OWFS' is mainly that on eg. a raspberry pi the Onewire plugin + kernel driver can use a GPIO pin to connect directly to the onewire network (with the aid of one resistor), while using OWFS + owserver requires a hardware bus master, for instance a usb-dongle, which adds to the price of the setup.

Onewire plugin configuration: https://github.com/motoz/PellMon/blob/m ... ewire.conf

Another new addition is pellmonconf, a web based text editor for the configuration files, that simplifies editing the configuration files.

Det lyder godt.

Vil give det endnu et forsøg når jeg lige får tid igen
