How to share values between LM in diferent buildings (secure way) - batistacaceres - 15.03.2022
Hello:
I need to share values between group address from different logicMachine located in different buildings. Whats the best way or the best protocol, (the best secure) to get it??.
best regards

If they are located on same network you can use KNX IP secure. If they are not then you can use MQTT but you need broker somewhere. You can even use our cloud. If you add all LMs to the same cloud network then objects added to cloud will exchange data. Objects added to mosaic are the one exported to cloud or you can tag objects with tag 'lmcloud'

Thank you Daniel:
They are not on the same network, maybe cloud solution is a good idea thank a lot...
I'll expose what I want for any other comments, all ideas are welcome.
I have one logicMachine like "Master" and others maybe 20 like "Slaves", reporting its status, ones an hour. Now the LM "slaves" comunicate it status using remote services:
http://remote:remote@192.168.0.10/scada-remote?m=json&r=grp&fn=write&alias=1/1/2&value=true
but I want to know if there is a better (secure way) to do that because I dont want to send user:password by url ..... thinking always in security. Is there a way to send that password encripted? or may be i am demanding so much, and all of this is not fully necessary.
Sorry I ask this from my ignorance on the subject.
best regard..., and thank all...

You can use HTTPS for remote services.

If you are trying via browser you might see a security notification that a self-signed certificate is used. You have to accept it and it will work. No extra configuration is needed from LM, just change http to https in your script and it should work. There's no other way to pass credentials but to set them in the URL. But if you are using HTTPS it will be encrypted.

Hello admin
I try the remote service via the browser and its work.
but how to use it in the script?
I use this SCript
Code:
require('ssl.https')
ssl.https.TIMEOUT = 5
-- Read from object
local reply = ssl.https.request('https://remote:remote@*.*.*.*/scada-remote?m=json&r=grp&fn=getvalue&alias=62/7/30')
log(reply)Where should I but the username and password and what is the format?
Admin username password is something like "P@s0ord"
RE: How to share values between LM in diferent buildings (secure way) - admin - 01.07.2022
Like this:
Code:
http = require('socket.http')
mime = require('mime')
result = http.request({
url = 'https://*.*.*.*/scada-remote?m=json&r=grp&fn=getvalue&alias=62/7/30',
headers = {
Authorization = 'Basic ' .. mime.b64('remote:P@s0ord')
}
})
log(result)RE: How to share values between LM in diferent buildings (secure way) - khalil - 02.07.2022

log what the http request result/error is:

res, code, hdrs, stat = http.request({ ... })

Do you have Export set for this object? Alternatively you can disable "Allow only exported objects" in Remote services settings.

Hi.
I don't get it. I put this code:
Code:
http = require('socket.http')
mime = require('mime')
result = http.request({
url = 'https://XXX.YYY.VVV.ZZZ/scada-remote?m=json&r=grp&fn=getvalue&alias=32/7/1',
headers = {
Authorization = 'Basic ' .. mime.b64('remote:Password')
}
})
grp.write('0/0/16', result)
log(result)address 32/7/1 is 1-bit - true/false
address 0/0/16 is 1-bit - true/false
in log i have:
* string: false
but address 0/0/16 is true
if i use function toboolean is still true on 0/0/16
what im doing wrong?

You need to decode the received value using JSON.
