RoomNode Temperature suddenly broadcasting negative figures?
21 October, 2012 - 19:05
Today ‘out of the blue’ the temperature sensor from my RoomNode switched from Positive to Negative values please see the attached 2 screen shots, I’ve tried removing the batteries from the RoomNode to see if this might reset it, it hasn’t so far. Can anyone help/advise?

Found the problem and a soloution
Check out this thread :)
http://www.homeautomationhub.com/content/temperature-measurement-hahnodes
I cannot figure out how to upload files to here so download
http://www.packetradio.co.uk/jeenode0to100.zip
and put the contents (after unzipping) into \etc\plugboard
seems ok on my setup (which is the same as yours as i sent you my jeenode applet. (but my sensor never goes over 50 as i cannot get it close enough to the middle of the tank :()

Tried it on my system nd it went negative
anyone shed any light?

Here's mine that works
Feed 6 on https://cosm.com/feeds/13194?pachube_redirect=true - should really be called tank node - 'cos its measuring
hot water tank not the boiler temp.
I have two luas in plugboard - called "boilernode" and "jeenodeApplet.lua"
Note this is running off a second livebox as you can see by the "target="dbzoo.livebox.2.serial" - in the jeemon section of
the jeenodeApplet.lua file
1. boilernode.lua contains:

So it looks like you need the extra Node ID definition.
Hope that helps - still very much learning at this end

F.A.O Kim
Kim i read your reply but did not really understand it? what should i add?
I think that it could be caused by a "naming" thing-testing this now by having the same contents of LUA with 3 different names in plugboard BoilerNode.lua boilernode.lua and boilerNode.lua
and tidied up my jeenode.lua (copied below)

Sorry I've not been around
Sorry I've not been around much lately.. Busy moving house (AGAIN!) should be all done by this time next week.
I'm pretty sure you are hitting the 10bit boundary that is reserved for the room nodes, which will happen once you go above 51.2 degrees. For a room this isn't an issue as I doubt anybody is going to heat themselves up this much but if you are using it to monitor a boiler then you need to use the modified BoillerNode that works around this limitation. So as to go from 0 -102.4 degrees instead.
Alternatively we reflash the roomnode and increase the bit precision AND the LUA module to suit and create a new Node type so as not to disrupt existing installations.
Update: To be clear the bug an be fixed by modifying the LUA decoder. You can workaround this limitation. I already did this for Kim and documented how to go about installing the new "BoilerNode.lua" which is a modified "RoomNode.lua" are we having problems using this? Because this is the way around this problem.

g7pkf let me explain this
g7pkf let me explain this line.
BoilerNode = require("boilernode").BoilerNode
This create a BoilderNode VARIABLE (which is a class reference) from the file "boilernode.lua" using the Class inside that file BoilerNode. So you only need a file called "boilernode.lua" on your system - remove the others.
You then need to USE this BoilerNode, or constructor in technical terms, to set the appropriate endpoint.
local nodes = {
[2] = BoilerNode{base="dbzoo.livebox.jeenode:pond", endpoints={temp=1,light=1,lobat=1}, ttl=1800},
}
Its just like that. You did no use the NODE in your code you continue to use the RoomNode --- note the BUG is in the roomnode.lua decoder which is why you replace your RoomNode endpoints with BoilerNode endpoints..

Thanks Brett
One small word can make all the differance :)
Double speed just cange the node at the bottom of the roomnode.lua.
seems to not fail but i am away so cannot test if it goes -ve?
sorry

Yes
So it now looks at the Boilernode lua not roomnode lua for data (thats as i understand it anyway)

sorry ....
.... I have been on hols with no wifi so have missed all the fun. Glad you got it going.
