I have the zeo decoder viewer 0.3a source, and have done some fixes to it to get round some of the issues you hit upon (the time to z, and also some other problems than fix problems for the PC viewer). If you want the 0.2a source I will see if I have a copy of that as well (although I didn’t bother with fixes with that).
I did do an updated jar for someone that wanted one that have those fixes in:

– corrected the URL!
Thank you woodinblack & Jay Aitchsee!
@Zimmerma379, Doe this help? It’s from the Zeo Decoder Docs.
4.4 Field Specifications
4.4.1 Time representation
All date and time values are represented using a consistent format described here.
For XML the dates and times are specified as composite tags containing the following
nested tags:
year
month
day
hour (24 hour time)
minute
second
Each tag indicates an integer value. In the human readable format the date and time are compressed into a single line of Field = Year-Month-Day T Hour:Minute:Second (UNIX timestamp value).
In cases where only the time of day is relevant (and the date is not relevant) the date is set to 1970/1/1. In these cases the year, month, and day fields is ignored.
In any case where a null time and date is to be specified, none of the six date or time tags will be present.
Hi
Sorry, trying to get some help finding the post with the most up to date information and thought it was worth asking rather than re-reading 316 posts…
You may recall when I first read that board that I only had the mobile unit, but I finally managed to get hold of a bedside unit a few months back. I checked the firmware version, in a rush, and thought it had the latest unencrypted version 2.6.30, but actually, I’ve checked again today and it’s actually 2.6.3. Bah!!! Is there any way to recover the months of encrypted data? I’ve read the instructions in post #90 which suggests I’ll have to delete all the saved data when I upgrade to 2.6.30, but I was encouraged by zimmerma379’s post #312 which suggested he had unencrypted some data from prior to his firmware upgrade… Can anybody point me at which post describes how to do that??? I realise I’m clutching at straws and it was my own dumb fault for not checking the version properly, but, you know… I’m fallible!! Otherwise, I’m starting from scratch again!
Thanks!
Jane
Jane, go here to my resources post #156 and toward the bottom of the page you’ll see a link to @bo3bber’s decrypter. Just make a copy of the zeosleep.dat file first to be safe.
When you get ready to install the decode viewer, @woodinblack has repaired and corrected the zeodecoderviewer 0.3a. His version is zeodecoder W0.4a which can be used in place of the original 0.2a and can be downloaded from his link in post #315.
You might also want to look back a few posts at post #313 by @woodinblack for a preview of a new viewer he is working on.
Is anyone still interested in updates on using disposable electrodes? I’ve posted about them a couple of times (#284; #161); this information is still valid, but I’ve progressed a bit in fine details of technique since then. I’m trying to see just how long I can get; so far I’m up to 18 days with a single set of 3 electrodes from a long-open pack of outdated disposable electrodes, and they’re not (quite) dead yet. Personally I’m happy with disposables, and not having to try to make or acquire headbands; and with this lifetime they’re not at all expensive. Possibly more people “out there” will persevere with Zeos if they know that they work with electrodes that are easily available and inexpensive (if they hear abut it). I don’t come here all that often, but if there’s interest I’ll write up some further details next time (electrode lifetime testing takes a long time). Techniques: Hypafix 5cm tape, Tensive gel (optional, for ~double life), and a moist finger (optional, for a few days longer life).
Awesome news on this front! I am definitely interested and can help out with some coding if need be. In terms of a backing store for your options, what about having hooks to the end user’s cloud drive, such as Google Drive, LiveDrive, DropBox, or something like that? Then you could point the PC-based windows app to the same data store as the mobile app? The user could have “settings” where they could point to the physical location of their data store in the cloud - maybe the apps could impersonate them or if you wanted to get real fancy you could put hooks in your app so they could allow / permit it to access their data in their cloud drive.
I like the idea of a PC based app as well as a mobile app (different capabilities). I also think giving users a way to “share” their data from their personal data island with other users of the same app or with 3rd party systems would be a great feature. This could be a one-time data transfer or on some sort of scheduled frequency / real-time.
Ultimately, if users had some peace of mind knowing their data a) belonged to them, b) was backed up online, c) wasn’t going to die with a given service, and d) was always available to them forever - I’m guessing more people would be willing to jump onto your system and give it a shot.
Just some thoughts; hope you’re able to make this a reality!
Is anybody know how to open Zeo Mobile to change battery? Mine is too weak and dead by earlier morning.
Where to get Zeo Mobile Update? I see that 0.0.70 version exists, but mine 0.0.56. I checked webarchive, but it don’t have any .exe files.
A negative answer here might be a bit better than no response at all: I’ve searched the Web several times, and never found any information about changing a Zeo transmitter’s battery. Anyone with a dead one can try to work out how to open it, then see what type of battery is fitted and cobble up a replacement. As replacement transmitters aren’t available, it’s unlikely that anyone will risk destroying a working one. I’d expect it’s likely that both the bedside and mobile transmitter will have similar battery arrangements. If your transmitter is quite useless and you don’t want to open it, maybe somebody in this forum in your region would care to try? HTH
I have finally got to a point with my zeo data viewer application where it provides more information and is easier to use than the Java application, so have decided to post it to enable others to use it.
There are additional features I would like to add but it is in a state where it is highly useable. Anyway, I thought it deserved its own thread, so I posted it here.
and the software itself can be downloaded from:
Continuing the discussion from Zeo Sleep Monitor:
Jane, my assumption is the wear out mechanism is a combination of dirt and the conducting material being worn off the metallicised cloth. To clean, Zeo recommended hand washing the headband and sensor pad (without the pod) with a delicate fabric cleaner, such as Woolite. When asked by a consumer, they also said a rinse in rubbing alcohol should be OK. Zeo’s 90 day replacement policy was based on the anticipated wear of the silver fabric in the sensor pads. I have rinsed mine in an alcohol bath, seemingly without harmful results, but I’m not sure it did any good, either. I never tried washing in fabric cleaner. You might try an alcohol pad wipe to the forehead before donning the headband and/or a wipe of the pads themselves. Lately, I’ve come to think that a little sweatiness might actually improve the sensitivity of the pads.

So do you have a link to what you do and where you get this stuff from?
I get the information stuff from all over the place. I posted details in postings to this thread, #322; #284; and the most detailed post (updated a few times), #161. Most of the results are from what Wikipedia decries as “original research”; I’ve seen no reference to anyone else using one set of three disposable electrodes for more than two nights. I have managed to get 20 with special care, and routinely get over 10 nights.
I get the physical stuff from eBay advertisers (Ambu Blue P electrodes) and Amazon (Tensive, Hypafix).
Also a brief summary at
Sorry, probably not clear, I meant a link to a web page or anything, and where you got the physical parts from.
Thanks, will look into it as we have had over a year on the current sensors (although it doesn’t seem to be showing any signs of degrading yet)
I did answer, interpreting “stuff” both as information and materials in separate paragraphs! The thing is that I can’t give you any specific link. I’ve looked at the specification sheets for Ambu electrodes, manuals for nurses on ECG electrodes, an instructables page on third-world disposable electrodes using beer bottle caps, flour, and salt; various articles on ECG electrodes; and so on. I haven’t kept links to many, just picked up little bits of information, like the idea of roughening skin with a towel after washing forehead. Quite a bit of the stuff I say can’t be found anywhere (how to convert Ambu electrodes with the wrong connector, differences between types of surgical tape).
In other words, as far as I know there is NOWHERE on the Web you will find any information relating to Zeo which describes getting more than two nights from a set of electrodes, or how to extend their life, or just about anything on non-Zeo-branded disposable electrodes… Postings in this thread 160 (most detailed), 282, 320, and recent ones, are the only source I know of. There is quite a lot of information in various places on making Zeo-compatible long-life headbands with sensors (using the original Zeo transmitter, for which there is no replacement).
Perhaps I should claim 20 nights as the world record for duration of disposable electrodes with Zeo, beating the previous record of 2? I have no interest in being world champion, but this might provoke others in trying (probably successfully) to beat me!
Some of the links from my notes (unchecked, may not be useful) are:
Specification sheets on Ambu electrodes
Parker Labs instructions on application of Tensive.
Various Amazon and other reviews on Ambu electrodes, Tensive, and Hypafix, and other forum discussions on them.

I’ll try and answer anything you ask, but that’s pretty much a complete set of links relevant to electrodes from my notes.
Thanks for all the sensor advice. I decided to start small and wiped the fabric contacts with antiseptic (alcohol) wipes last night. The wipes ended up pretty grubby but I had a worry I was damaging the conductive fabric as much as removing residue! So I was quite pleasantly surprised that the sensor still worked! With the new viewer I can now determine that I did get one drop out last night, of a few minutes, but only one. Before that I’d been regularly getting a few short and an occasional longer drop out per night. Will try the same routine again tonight, see if I can establish whether the sensor is recoverable or at least doesn’t get any worse. I’m still at the point of having two new sealed headbands to use, so I can effectively sacrifice this one if it helps to establish how to get the best performance out of the others!
Jane
Quick update: tried wiping the sensor fabric contacts with an alcohol wipe again last night and the viewer shows me that there were no drop outs in my data at all last night

YAY![/size]
Thanks, that’s very useful information. One of the problems with reviving headbands is the risk you’ll make them worse. It would appear that an alcohol wipe helps to remove gunk but doesn’t affect the electroconductive silver. It would be useful, in the fullness of time, to know the ultimate life of the electrodes on headbands - it might be very long if the silver isn’t actually removed/eroded. Maybe when wiping no longer works a liquid alcohol (ethanol, isopropyl, of good purity, to evaporate without a trace) might extend the life? Zeo recommends washing in water (I don’t remember the small print), though alcohol is a better degreaser, I wouldn’t want to experiment with detergent in water. If I’d known this I might have delayed moving to disposable electrodes when headbands stopped being easily available.
