Intergas Incomfort Heater control

[sexyboy]

Hi guys,

Im about to get an intergas boiler installed and I was wondering what info can you get off the LAN2RF gateway.
It seems like the gateway has an api.

Thanks in advance.

[Eddiever]

A friend had an unused Incomfort gateway which he gave to me. I have it connected to my network and I can connect to it through the android app and also the webbased version. However if I set it up in Domoticz -> hardware -Intergas Incomfort lan2rf gateway with the correct IP address and portnumber 80 I get:

Code: Select all

2019-04-17 17:15:49.383 Error: InComfort: Error getting current state!

Does anybody have a solution for me? Am I using the wrong port? I really don't know right now.

Second one, does anybody has the API documentation lan2rfgatewayhttpinterface available? The link mentioned earlier in this thread doesn't work.
http://www.filedropper.com/lan2rfgatewayhttpinterface

And yes I know this is an old thread but I think my issue relates perfectly to this one.

[Eddiever]

If I put in:
http://ipdomoticz:8080/json.htm?type=co ... =0&Mode6=0
then I get this in my browser:
{
"status" : "OK",
"title" : "UpdateHardware"
}

Maybe this gives anybody a clue?

[Eddiever]

Ok, my firmware of the gateway is IC3-1-ICN-V1.17. With this version it is required to give the login details. If I access the gateway like:

Code: Select all

http://user:password@ipaddress_gateway/protect/data.json?heater=0

Then the respons is:

Code: Select all

{"nodenr": 78,
"ch_temp_lsb": 225,
"ch_temp_msb": 10,
"tap_temp_lsb": 153,

"room_set_ovr_2_msb": 0,
"room_set_ovr_2_lsb": 0,
"rf_message_rssi": 29,
"rfstatus_cntr": 0}

But I am not a coder but I am willing to try. But where to begin? Anybody who can help me get started?

Code: Select all

http://user:password@ipaddress_gateway/protect/data.json?heater=0

But I am not a coder but I am willing to try. But where to begin? Anybody who can help me get started?

thank you for clearing that up, I didn't know it needed login information.

i put:

Code: Select all

user =  'admin'
password = 'password'

in the "config" part of the code

and:

Code: Select all

url= 'http://'..user..':'..password..'@'..lan2rf..'/protect/data.json?heater=0'

in the '"functions" part of the code i put "--" in front of

Code: Select all

url='http://'..lan2rf..'/data.json?heater=0'

to exclude the code (deleting would also be fine)

now i can read out the temperature of the thermostat.

i hope this helps

[Eddiever]

@WideckNL, Thank you for your information. I am running Domoticz on my NAS and use a precompiled version. As I mentioned before I am not a coder but willing to try. But which file do I need to change?

[WideckNL]

i dont know about installing on a NAS but here is what i did;

I took the files provided by Jeroen Zeist in the first post. ps. thanks Jeroen!
"Intergas Incomfort Lan2RF control 1.1.zip"

copied them;
script_time_intergasincomfort.lua
script_device_intergasincomfort.lua

to /home/pi/domoticz/scripts/lua you should find your domoticz folder somewhere on your nas.

you can open these files with notepad and edit like i said in the previous post.

[Eddiever]

Thanks all for explaining especially WideckNL!

For anyone who needs this also here is what I made of it. All credits to JeroenZeist!

[stingone]

Got it working. The JSON file path was not correct. does anyone has a script to read-out the pressure etc?

[Eddiever]

@stingone,

Do u still need the script to read the waterpressure?

[Krijn20345]

Hi,

I'm running this script for quite some time now and it works like a charm.

Currently I'm switching to Dzvents and I'm going to try to convert this script.

I was wondering if someone already pulled off to retrieve pressure data etc?

[Eddiever]

After working like a charm I have got some issues with my Incomfort gateway. Don't know why but all of a sudden I only receive the value zero (see below). I have changed the position of the gateway, closer to the boiler. Then it worked for a few days and then the zero value is back. Ofcourse I powered it off, leaving it for 10 minutes and started it again. But still problems. Any ideas what could go wrong?

[Smintyboy]

I use the buikd in plugin and is working okay. I can see the temperature, pressure, setpoint, etc. But can't set the override setpoint. when I set for example 20 degrees, the log file says:

InComfort: Setpoint of sensor with idx idx changed to temp

what can I do to solve this ?

[Dutchhornet]

The script is working fine for me. Thanx.

[Tristan]

Does this work on the newer gateway or only on the older version?
Second question is what happens if you do not have internet (like for some days) does it still work. Or do you have to be always connected?

https://www.intergas-verwarming.nl/app/ ... 014-00.pdf

Second question do you need an internet connection or can you still communicate when internet is down?

Script for updating Gateway when thermostat setpoint is changed in domoticz.

Code: Select all

                                     -- DzVents script for updating setpoint of LAN2RF Incomfort Gateway Intergas
                                    -- V1.0 (september 2020)
                                    
local IPADDRESS = '192.168.11.12'   -- IP address of LAN2RF Gateway
local USER = 'admin'                -- login credentials LAN2RF Gateway
local PASSWORD = 'admin'            -- login credentials LAN2RF Gateway
local THERMOSTAAT = 'Thermostaat'   -- Thermostaat domoticz device name


return {
	on = {
		devices = {
			THERMOSTAAT,
		}
	},
	execute = function(domoticz, device)
	    domoticz.log('Thermostaat setpoint was changed, updating LAN2RF Incomfort Gateway', domoticz.LOG_INFO)
        
        -- Calculating setpoint (see Intergas API documentation)
        local SetTemperature = (domoticz.devices(THERMOSTAAT).setPoint - 5) * 10
		-- Update LAN2RF Gateway
		domoticz.openURL({
			url = 'http://' .. USER .. ':' .. PASSWORD .. '@' .. IPADDRESS .. '/protect/data.json?heater=0&setpoint=' .. SetTemperature .. '&thermostat=0',
			method = 'GET',
			})		
	end
}

Hi DeKraker

I implemented your script and it works about 90% well
Except for 1 problem, when manualy setting the honeywell round thermostaat the value of local THERMOSTAAT = 'Thermostaat' is only updated silent.
That way the Set_temp Override in the gateway holds the old value and the temperature will be set back to the old value after a few minutes.
So using this script means i can not use the manual thermostat...

Maybe you can send me a PM so we can talk this out in dutch?

I have written a script in DzVents specifically for the LAN2RF Incomfort Gateway running the latest firmware.
The script is based on the API documentation provided by Intergas.

Script for requesting data from the gateway and updating domoticz devices accordingly.

Ok, i have to get back on my last post.
The script does not work as should be expected. For example last night the thermostat was set to 30 degC in the middle of the night without any reason or manual input... And the night before, it was set back to 4 degC also without any logic behind it...

Thanks all for explaining especially WideckNL!

For anyone who needs this also here is what I made of it. All credits to JeroenZeist!

Script_time-Intergasincomfort.lua
and script_device_intergasincomfort.lua

All I did where some minor changes to get it working on my NAS (thanks WideckNL).

So i implemented this script with some minor improvements and all seems to be working fine so far.

I have an Intergas Xtreme30 heater together with the Intergas gateway and thermostat. I run domoticz an a Pi. I have added the scripts and I can change the temperatur in Domoticz now but I can not change the temperature now with the app or thermostat or on the heaters (local) webpage. Within 30 sec it is overruled by the domoticz setting again. Is this normal ? Or does it mean that my settings are not ok ? I added 2 virtual temperature sensors and a virtual thermostat and setted these in the scripts. But the 2 virtual temperature sensors will stay at 0. Or should I use the already used IDX from the Intergas Thermostat ?
