new: KMTronic USB/485/TCP(Web) support

[ayasystems]

Kmtronic allows you connect at Nopen and NClose.....

Could be possible set as normal or inverted the Kmtronic devices?

For this devices that normally are ON all day I'm ussing NClose but in domoticz it is showed "Off" when really is "On"

Regards

@miroslavpetrov, dont know why this is happening to you, but it does not make any sense, as these are out-side processes, nothing todo with any hardware.
So this should not happen
And you should also try the beta version then

I know it does not make any sense but as you can see other user also faced that issue...However, it is fixed in the Beta version.

Hello,

Currently all my lights are controlled with teleswitches (a short 220V pulse inverts the relays). I'd like to expand my Domoticz system to control the lights. To do that:
1. I should be able to invert the teleswitches
2. As I don't know their initial state, I should be able to check if current is sent to the light: I imagine to convert 220VAC to 5VCC and then to action a relay (difficult to find relays with 220VAC relay coil)

In both cases the load will be extremely low and I was told that for such low current golden relay contacts are necessary. Would Kmtronic relays are adequate in my situation ?

220VAC --> 5VCC conversion is not very clean. Another idea ?

Thanks

Hi,

is it possible to add support for this UDP box as well:

http://info.kmtronic.com/lan-ethernet-i ... board.html

It uses exactly the same protocol as USB version, but is just listening on a UDP port 12345.

I'm stupid and bought it before checking if Domoticz supports it or not..

[Derik]

mmm
See this KMTronic in the hardware list... I see it is a relayboard. [ i now what i can do with a relaisboard ]
Only what are the options when i add this hardware?
Do i get standard devices?
Or what is possible with this hardware...

[Derik]

Dear all..
Please a little information..
How can i use this board.
Perhaps a http push action possible?
Or just on and off?

[jono]

Since version #2434, Domoticz now supports the KMTronic USB and TCP(Web) relay boards.

They are not expensive, and the hardware devices look very professional

Supported:

USB:
1,2,4 and 8 channels
* needs external 12 Volt power supply with more then 1 channel

TCP(Web)
2 and 8 channels
* needs external 12 Volt power supply

More information is available at:
http://kmtronic.com

I cannot get mine to work 8ch lan relay board labeled Domoticz and get the following in log any ideas ?

KMTronic : tcp/ip worker stopped
KM Tronic : stopped

Thanks in advance

hi all

I’ve recently brought a DOMOTICZ LAN Ethernet IP 8 channels WEB Relay board I have configured my router ports settings and fire walls works perfect ,

but when I tryand integrate it with Domoticz selecting KM tronic LAN interface in hardware domoticz docent recognise the box in devices

Any ideas ???

Hello,
Any plans to support the KMTronic LAN DS18B20 WEB Temperature Monitor too?
Thanks

I have written a little LUA script to read the temperature values and put them into virtual temperature sensors now if it is of some use to someone.
It is my first attempt at LUA so let me know if you think it can be modified/improved on.

Runs several times at once (from what I see in the log file) and I don't know why. If you do let me know.

Thanks

Thank you for the work.
I have some problems with the script, I have about 2 years the Kmtronic temperature monitor for a wood boiler puffer control. This solution is a great job. Can you contact me via PM and give me your e-mail for some questions? Thank you very much and a Merry Christmas.
Jack

Edit:

When i post the script LUA in Events i get this message:

LUA: Bad XML status read - temperatures NOT updated

What's the problem?

Thank you

[RATA1]

Turn on debug in the script and see what is printed in the Domoticz log. Looks like it is not reading anything back to throw that error. Have you changed the ip@ of the relay box and not updated the script? Can you web browse to the ip of the kmtronic and see any output I.e. http://kmtronic-ip@/status.xml
The script hasn't changed so it is not getting or reading something right.
Mine have been fine and I am running three on the latest Domoticz beta so check your output from kmtronic box.
Cheers.

It prints out in the general log - it's an option under right hand menu (settings) at the bottom.

Maybe I forgot some pass?

I installed Domoticz, after on Setup - More Options - Events I created a "Board1", Lua, All, Event active (V) event, and your script compiled and modified in its parts. After I saved.

[RATA1]

This bit is reading nothing back or the string is not being populated so there is nothing to progress in the script - hence the error you ate getting. I did have an issue ages ago with a beta version that broke them as the data was empty/corrupted. If you have updated recently this might be the issue.
There was no explanation for why this happened as the beta version should not have done anything but it did.

Sorry I can't help more at the moment as it appears to be a variable issue in Domoticz . Upgrade or roll back or ask a dev to help?

I installed Domoticz, after on Setup - More Options - Events I created a "Board1", Lua, All, Event active (V) event, and your script compiled and modified in its parts. After I saved.

Ok. I don't write/create/use it like that in the script editor like you have done. I use it in the script folder under domoticz folder as a time base script as a txt file saved as a .lua- don't recall where exactly as I am wrapping presents. Maybe you need to do it like that and not the editor but can't see why as I use the editor for other scripts just fine.
If it has never worked then it will need some investigation. Are the Domoticz and the board on the same network and reachable?

No password needed far as I know.

I have already created the script_temperature_Board1.lua file with the code you have created and modified.
But once open domoticz, no feedback.
At the temperature tab "No Temperature sensors found or added in the system ..."
I would not know what else to do..!


In fact, the PC on which Domoticz is installed is under a network (10.10.1.x) while the board in another (192.168.1.x), however, is easily reachable.
Can this create problems?
