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

[gizmocuz]

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:

A quick Fleabay search turned up these too http://www.ebay.co.uk/itm/KMTronic-USB- ... 3f45f29380
Will they run from a rfxtrx? They come with their own little 433mhz transmitter... it all looks promising

Working on this one, i am having issues opening the COM port... still have to do some testing under linux

Once implemented i will send them to RFXCom, maybe they are able/willing to implement it.
They are using a C1101 433Mhz tranciever from Texas Instruments

Now also implemented the RS485 (USB->485) version.
With this you can control up to 48 relays from one converter unit (and 6 devices)

Excellent! These look to a very useful set of tools!

Hello,

I'm just update to v2.2493 and i add my Kmtronic web relay in Domoticz
Before I managed it with lua scripts, php and virtual switches.
My Relay board is used to control my electric heaters.

But the operation is not the one expected
If I send the OFF command with JSON, it's toogle to ON if the relay is already OFF
If the relay is ON, the JSON command ON toogle it to OFF

Every Json command (On or Off) toogle the realy...

Hi,
I`m using USB > RF433MHz > 8 Channel Relay Board http://kmtronic.com/usb-rf433mhz-8-chan ... board.html it is working, but if there is no activity for some time, command is not done and I have to send command twice. It looks that there is so "stanby" mode, if device is not used. Do you have any idea how to solved it?

Thanks

Hi,
I'm also having this same issue, it seems to go to sleep after a while, would using the data time out be of any use for this issue or is that for some thing else, i'm also having a problem using the on off delay as they don't seem to work on the kmtronic stuff, works fine on the lightwaverf stuff.

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

Hi Rata,

thanks for script, I'l try during week and let you know

[Mazzokun]

Hi all,
I have RS485 (USB->485) 16 relay . The software recognize them and I can manual on/off the single light, but timers, group on/off, blocky etc. doesn't work anymore.
Tried with raspberry pi or mac stable/beta but doesn't work anymore.
Is there some bug for RS485 (USB->485) ??
Thanks

[jono]

Morning im new to Domoticz

i have a KMtronic Lan Web 8ch relay connected to my Broadband router domoticz is operated on raspberry pi 2

i have set it up in hardware and i can see the relays in switches

but the problem is when i switch the switch the relays dont operate ?? any ideas

[paulpatta86]

Hi.
sorry for my english. i am italian.
i have kmtronic temperature.

I created the script in the events of domoticz
replaced ip, id and name of sensor
but script rata1 don't work.
please help me.

Have you managed to fix this issue? I am currently looking at these boards to use in a project.

in the beta release it works without any issue

[miroslavpetrov]

I received the RS485 boards and tested them using the latest Raspberry image and as Mazzokun said groups, scenes and blockly doesn't work with the boards. However I wrote simple bash scripts that send serial commands to the boards which fixed the problem.

[ceetn]

Is the RS485 board an easy and suitable solution to control the lights in my garden? How easy is it to get this working on a raspberry pi with domoticz? Can somebody show me what the config looks like for the board?

Hi,

In the current stable version of domoticz, when you add the RS485 board in hardware, blockly, timers and some other things stop working...However, if you write simple bash scripts and assign them to a virtual switch, everything is fine. And for ease of use, they are plug ang play. You get a USB ->RS485 converter which is recognized automatically from the Rpi, for windows you have to install drivers.

[gizmocuz]

@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
