dzVents updateSetPoint errors out

Posted: Tuesday 18 July 2017 23:49

the call to a setpoint device gives:

2017-07-18 23:41:40.605 Incoming connection from: 127.0.0.1
2017-07-18 23:41:40.610 Error: Error opening url: http://127.0.0.1:8080/json.htm?type=com ... etpoint=16

388 is indeed the id of the device I am trying to change. Thoughts?

browsing through the code, I noticed it uses a setsetpoint json call which I could not confirm through any docs. Mayve switch to a udevice call instead as follows:
current:
/json.htm?type=command&param=setsetpoint&idx=' .. device.id .. '&setpoint=' .. setPoint
suggested:
/json.htm?type=command&param=udevice&idx=' .. device.id .. '&nvalue=0&svalue=' .. setPoint

I know the last works as I already use it.

Hi,

there was a change in dzVents 2.1.0 regarding Thermostat Setpoint update command - beta v3.8088 and this commit onward:
https://github.com/domoticz/domoticz/co ... 05685036ba

What type of device is your thermostat ?

It's a nest with a basic thermostat/setpoint device

Mm. that's unfortunate indeed. I'll have to make a distinction in the adapter for dummy devices that can work with param=setsetpoint.
Can you both try this: find the adapter (path/to/dz/scripts/dzVents/runtime/adapters) thermostat_setpoint_device.lua and change the code with:

Code: Select all

return {

	baseType = 'device',

	name = 'Thermostat setpoint device adapter',

	matches = function (device, adapterManager)
		local res = device.deviceSubType == 'SetPoint' and device.hardwareTypeValue ~= 20 -- rule out opentherm
		if (not res) then
			adapterManager.addDummyMethod(device, 'updateSetPoint')
		end
		return res
	end,

	process = function (device, data, domoticz, utils, adapterManager)

		device['SetPoint'] = device.rawData[1] or 0

		function device.updateSetPoint(setPoint)
			local url

			-- send the command using openURL otherwise, due to a bug in Domoticz, you will get a timeout on the script

			if (device.hardwareTypeValue == 15) then -- dummy
				url = domoticz.settings['Domoticz url'] ..
					'/json.htm?type=command&param=setsetpoint&idx=' .. device.id .. '&setpoint=' .. setPoint
			else
				url = domoticz.settings['Domoticz url'] ..
					'/json.htm?type=command&param=udevice&idx=' .. device.id .. '&nvalue=0&svalue=' .. setPoint
			end

			utils.log('Setting setpoint using openURL ' .. url, utils.LOG_DEBUG)
			domoticz.openURL(url)
		end

	end

}
And see if that works for both of you?

Hi Danny,

works for me - dummy device and Z-wave thermostat both updated without errors.

Thank you

weird: whilst it now uses a udevice command, the command itself gets truncated??? instead of param=udevice, it shows:

Hi heggink,

I see chaotic URL in my debug log too. I think it is only problem of web gui - browser misunderstanding of & characters. Try to look to text log of Domoticz (if enabled -log... command line parameter) or syslog (systemd journalctl)

Hey mivo,

You are absolutely correct. The log shows that the url is not garbled. When issuing the command via curl, it says "unauthorised". Turned out I did not have localhost in my settings not requiring a password. Works fine now!

Thanks!

Ah, yeah, that's in the docs under getting started :-D
Add 127.0.0.1 to the addresses not requiring a password.

Thanks for making that blindly obvious ;-). I have a bunch of headless Pi's (with fixed IPs) around the house so never use localhost hence never adding it.

Good news: I have now converted all of my old luas to the new dzVents including my motherofallluasinonebigfilebecausetheperformancecrapsoutothwerwise which I had to create due to the blockly memory leak.

Me happy :-). Thx!!!

BTW: retested and the setsetpoint DOES work ie the issue was my localhost security to begin with.
Apologies for chasing a red herring!

I have the same problem but cannot solve it by adding 127.0.0.1 to my domoticz setting.
If I take the JSON URL (the full one from the text log) that gives the error and open the url in my browser (substituting 127.0.0.1 with the direct IP of the Synology NAS Domoticz is running on) it does work. Why does the URL not work via Domoticz? :?

Code: Select all

Is it possible that 127.0.0.1 isn't accessible somehow on the nas itself? You could perhaps ssh to your nas and try a curl or wget to that address.

Updated my Synology and suddenly it works again! Thanks for the suggestion danny!
