I ordered a emonTH and 433mhz receiver for my raspberry pi from the official OpenEnergyMoniter store.
I chose a emonTH with a DS18B20 sensor only.
Unfortunately the sensor seems "stuck" and is only reporting a reading of 85 (presumbably this value is not scaled, but regardless it is wrong).
Here is some logging output:

---- end log output----
The temperature is 19.0 degrees Celsius and has varied througout today by a couple of degrees as I turned up the heating, but the emonTH has only reported 85.0.
What can I do to fix this?
Re: Incorrect temperature from emonTH
just FYI, I am running a rpi b+ and running Rasbian Wheezy with Emonhub software.
Re: Incorrect temperature from emonTH
Hello @nzpaul, 85 or -127 is the value reported if there is an error with the sensor or connection. Are you using the sensor on the board or the external encapsulated temperature sensor?
Re: Incorrect temperature from emonTH
I have not made any changes to it. I just added a two AA batteries. I looks like it has a DS18B20 soldered onto the board (I ordered it with only a DS18B20).
I have attached the photo of what my board looks like.
Re: Incorrect temperature from emonTH
Did you get these devices recently? Assuming you did I guess you have a emonTH v1.5 rather than a v1.4? and from the log output I'm also guessing it's a rfm69pi (or rfm2pi with rfm69 fitted) due to the number of faint packets received, Further more I'm guessing you are using the "emonpi" variant of emonhub but I cannot tell if that was purchased on a SDcard from the shop, included as part of a downloaded image or installed from scratch.
Can you show us any node 19 "emonTH" settings in emonhub.conf?
The default of
should convert the values "82 3" from "19 82 3 0 0 0 0 31 0" (node id is 19 and the remaining 10 are 5 integers in byte pairs) to 850 and the scaling of 0.1 results in 85.0 so it would appear the values are not being correctly sent from the emonTH.
Are you running stock firmware? Do you have a FTDI usb programmer? If so you could check the serial output as described at the end of the emonTH page in "Appendix B: Debug Mode / Serial output:"
I believe the value of 85 can suggest an open circuit so you should also check the temperature sensor is fitted?
In this v1.4 image the black 3 legged sensor is located bottom left above the mounting hole
and in this v1.5 image it's the just above the right-hand end 2 terminals of the green connector block
In both situations the sensors flat side should be closest to the PCB edge.

[EDIT - Started writing this before anyone posted and got interupted by phone call - sorry !! :-) ]
Re: Incorrect temperature from emonTH
@pb66
I have the new version judging by the photos. I purchased it last week. I took it out of the case and it looks like it is version 1.5.2.
I plugged in a FTDI programmer and this is the debug output I got:
11

DS18B20 Temperature: 85.00C, Battery voltage: 3.00V
DS18B20 Temperature: 85.00C, Battery voltage: 3.10V
I am running the emonhub software I installed from github. The reciever is the RFM69Pi 433Mhz Raspberry Pi Base Station Receiver Board. I have another off-the-shelf consumer 433mhz weather station, so that might explain the other traffic on the band.
I am just running the default conf file (with my API key added). This is what it says for Node 19:

Re: Incorrect temperature from emonTH
I found an old DHT22 clone I had lying around. I plugged it in and this is the output I get:
11
emonTH - Firmware V1.5.1

DS18B20 Temperature: 85.00C, DHT22 Temperature: 15.70C, DHT22 Humidity: 63.70%, Battery voltage: 3.10V
I assume the DS18B20 they gave me was a dud.
Re: Incorrect temperature from emonTH
I would say that is strong probability but it is probably equally possible a firmware glitch is the cause, I don't think the DS18B20 only is a frequent choice so cannot be 100% sure of the characteristics of that part of the firmware, but the sensor is being recognized so must be responding, yes it may have an internal error but it may not be being read correctly or even powered up in time for it's periodical reading.
Hopefully someone with more familiarity of that function will step in or I will explore later if I get chance.
Paul
Re: Incorrect temperature from emonTH
Can I reflash the firmware? where can I find it online?
Re: Incorrect temperature from emonTH
nzpaul, I think it probably is a dud DS18B20 although it is unusual. Do the soldering connections on the DS18B20 look ok? We will send out another to you today.
Re: Incorrect temperature from emonTH
@TrystanLea
I checked the soldering, it looks ok to me.
Thanks! Can I paypal you the cost of a DHT22 sensor and you put that in the envolope with it? I might as well play around with that as well (the DHT clone I am using with it now for testing is definitely not calibrated correctly)
My order number is #9192
Re: Incorrect temperature from emonTH
@TrystanLea I sent an email to the order support email address.

KINGDOM OF THE SPIDERS A film review by Andrew Hicks Copyright 1997 Andrew Hicks
(1977) 1/2 (out of four)
From "Arachnid Productions" comes this classic of horrible horror, starring everyone's favorite bad actor, William Shatner. He plays Dr. Robert Hanson, nicknamed Rack because... well, look at his chest. He's ripped! Actually, the name Rack has something to do with pool games he used to play with his brother, who was "killed in Nam."
Old Rack still takes care of his brother's widow and her small daughter, as we find out at the beginning, when a horse-bound Shatner ropes the widow. "Stop it.
He stiffens. "I may be a lot of things to a lot of people, but I'm not my brother." Not an actor, either.
We cut away from that to witness the first spider attack, perpetrated on a 200-pound calf owned by farmer Woody Strode and his wife ("introducing" Lieux Dressler). Shatner takes a look at the calf the next day and says, sadly, "The calf's dead."
"Ain't that a crock!" Woody laments.
"There's only so much I can do," Shatner replies, and you almost want him to say, "Dammit, Woody, I'm a doctor, not a veterinarian!"
Down the road, a redneck gas station attendant is in a similar bind. He goes into his shed to look for a tire and finds a tarantula instead. "Damn spiders are having a field day in here!" he exclaims, as another jumps out at him. "God almighty!"
Shatner asks for a reinforcement doctor and gets one in Tiffany Bolling, a sexy entomologist from "the university." Immediately, Shatner turns on the old Captain Kirk charm, asking her, "How would you like to have some dinner tonight?"
She replies coldly, "I probably will. See you tomorrow." Punked! Bolling heads back to her rented cabin, where she does what all hot horror chicks do sooner or later -- strip and take a shower.  "You're not supposed to live in people's houses," she tells it, in an almost baby-talk tone of voice. "You're supposed to live in the ground."
First thing in the morning, Shatner and Bolling pay another visit to Woody's farm, where Bolling finds their dog dead, announcing, "It would appear this dog died from a massive dose of spider venom."
"That would explain the spider hill," Woody replies, leading them to a giant mass of dirt out back that swarms with tarantulas. Shatner muses over it for awhile before heading back to his sister-in- law's house to flirt with her for awhile. Then he gets the idea that maybe he should burn the spider hill, and heads back to the Strode farm for the third time. As Woody lights it up, yelling out, "Burn! Burn in hell, you bastards!"
What no one counts on is the fact that there are 30 or 40 other identical-sized spider hills nearby, all of them swarming with killer spiders. Their natural prey has been cut back by prevalent use of DDT insecticide, so now they're coming after humans. Not just any humans -- humans who can't act. So in one hilariously bad sequence after another, townfolk die off, from the crop duster to Woody to the sheriff. There are even the requisite scenes of people wrapped in giant spiderwebs and screaming masses running out of the city while spiders run rampant. There's only one question on my mind; why the hell doessn't anyone just stomp on those things?
KINGDOM OF THE SPIDERS is awful, but laughably so. Shatner, complete with cowboy hat and oversize belt buckle, has never overacted more badly and the effects are so far less than special that this KINGDOM hearkens directly back to the unintentionally funny sci-fi flicks of the '50s. It's played out more as a slasher flick, though, and if you can track down a video copy of this rarity, you'll see previews for five or six horror films that seem even worse, with titles like THE TOOLBOX MURDERS, SCREAM BLOODY MURDER and THE DEMON.

Course Goal
Refine our understanding of XHTML5
Course Outline
- Polyglot
- Strict markup
- Rules of thumb
- Serializing
- Validation
- Further Learning
Pre-requisites
Understand HTML5 and its syntax
Polyglot: Strive to achieve
“A document that uses polyglot markup is an HTML5 document which is at the same time an XML document and an HTML document, and which meets a well-defined set of constraints.”
Use XHTML syntax along with new HTML5 tags
Flexibility of document choice
Loose vs. Strict
HTML5 is very forgiving about what it will accept
- checked="checked"
- checked='checked'
- checked=checked
- checked
- checked=""
- checked=''
Use first as rule of thumb.
Loose vs. Strict
XHTML more strict; higher standard
Good practices
Unforgiving (especially XML)
Browser will fix HTML5 errors to keep document usable
XHTML more error prone
IE doesn't mix with XML; tread lightly
Rules of Thumb
- Lowercase tag and attribute names
- Double quoted attribute values
- Closing tags to match opening tags
- Trailing slash on self-contained elements

Steps to Serialize
- Use correct MIME type
- Setup on web server
- Script with server side language
- <?php header('Content-Type: application/xhtml+xml;charset=UTF-8'); ?>
- Speciify Doctype: <!DOCTYPE html>
- Specify XML namespace
-
Validation
Good practice to check
Help improve markup
