Domoticz

gizmocuz wrote:@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

gizmocuz wrote: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

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

What does the debug output in the log?

Any ideas?


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.
