WTIU: Not able to load mth engine thru APP

Have you tried just setting the WTIU up with power and a small test track to see if that works?  That might help confirm if the unit is working and it is something else causing the issue.

In my post you'll see I tried that already. I get the same results!

I had a similar problem where I tried to add a new MTH engine in the app with my new WTIU and kept getting error messages in the app. I kept trying and on the 10th or so attempt it found the engine. Nothing changed during the attempts, so I'm not sure why it finally worked. If you're having a similar problem just keep trying to add the engine. Hopefully it eventually works for you as well.

Well, I am having same problem , can’t seem to add engines via the upgraded app using wtiu. I set up powered test track , have recycled wtiu many times and app many times and the app ‘ reads’ but keeps messaging no engine. Have tried 3 new PS 3 and a PS 2 MTH locomotive.Tried fixed out 1 and 2. Wtiu connected to android device using MTH wifi network with excellent signal.

Grrrrr!

Well, now I'm having the same problem. I was able to add one engine, but now I just get a "Request Failed" or "Request Time Out" message when I try to add an MTH engine. I just updated to the latest WTIU firmware as well.

Yes, I  also updated  wtiu firmware powered down wtiu and still unable to add engines .

Within the app I did a wtiu feature and factory reset , powered down everything and upon restart I was able to add two new PS 3 locomotives, at least on test track. So it seems it works now.

I also changed wtiu address to 5. Does anyone know if there is a requirement to set address within app to match wtiu or will it pick it up.

Everything seems to work now ….. until next glitch.

Hi again everyone! I found out that my WTIU never updated the firmware. Once again I went thru setting up for the MTH Network (being careful to follow each step & in the order posted) and was able to get to the actual downloading & installation of the firmware update. Once I was insured the firmware update actually download & installed, things started to fall in place!

MTH really needs to put together a step by step video running all the different ways to setup the WTIUs. The instructions you download for the WTIU from MTH can get confusing and in my opinion cause mistakes. A video would really help people with the different installations.

Transferred wtiu from test track to main layout, disconnecting the old tiu and everything works. Whew.Really strange that this device needs nearly two minutes to initiate and wifi signal to pop.Needed to add track power up work around .

I am having the same issue. I have downloaded and updated the WTIU firmware update, reinstalled the app and was able to connect one PS3 engine. I have tried 3 others and none of them will connect. I have tried using my home WiFi and the MTH network without success. Not sure where to go from here.

I’m still having the same problems as well. I’ve tried just about everything I can think of. I sent a tech support email over a week ago to MTH but still have not heard back.

If you are having troubles adding more than one engine please try deleting all the engines you added.  Then plug the power supply for the TIU to a different outlet then the power supply you are using to power your track.  That way the TIU is powered all the time.  Then after clearing the one or more engines you were able to add.  Make sure there is only one engine on the track at a time.  Add that engine.  After it's added take it off and put on the next engine and add it.  Take it off and go to the next engine.  Only add one engine at a time.  After all you engines are added then you can put the ones you want on the layout and hit the refresh circled arrow at the left of the name of the engine in the top left hand corner.

Also for those still having problems please state what power supply you are using and what device you are using so we can follow up if needed.

Thank you,

MTH

Thank you for the reply. I was ultimately able to add more engines, not sure how as I didn’t change anything, it just started working out of the blue. I am using 2 MTH power bricks into the 2 fixed channels and an Android based tablet.

While I seem to now be able to add engines successfully, I am having an issue where engines on the track are sporadically showing on the “inactive” list. Also, when I refresh the app to try to get them to appear as “active” I get the below message about every other time. If I keep refreshing it seems to ultimately work. This is happening on both the MTH network and my home WiFi network. When this happens I am maybe 8 feet from the WTIU. I don’t think it’s an issue with my network or the location of my WTIU as my base3 is in the same spot and I have no connection issues with that.

the app are far as I can tell from using it still has bugs. I cant rename the custom sounds at all. it just wont take when I hit save name. plus using the quillable whistle in a lashup freezes the lashup. the engines will not move and the sounds do not play at all.

I had an old tablet that had the app on it. it was an older app version and it worked better. then I upgraded the app on it to the latest version and got the same issues as the app on my phone. so its the current app version that need tweeking.

other than that btw my app which is the android version everything is working ok. my tablet and phone are sumsung and are not very old either.

I am starting to like running the trains more and more the more I use the app. the appeal for me at least is getting to the playable sounds and setting the individual engine ajustments. like sound volumes and smoke volumes and that whole page of settings. its so much quicker and more user-friendly than the remote.

I agree, it’s just buggy. Hopefully there is another update that will solve some of these problems. I too am getting really used to the app, and issues aside, am really enjoying it!

I am able to list all 10 engines I run on 4 different loops (+ a few inactive engines) on my Samsung SM-T580 tablet from 2016. I was able to run all 10 at the same time.I than tried loading the same trains on a newer Samsung SM-X200 from 2024 + my Samsung Galaxy A02s and am experiencing multiple loading/running issues with this tablet & phone. I'm still playing with them.

I'm also experiencing the AIU issue from another post. I have 4 AIUs, the WTIU sees them but I'm only able operate the switches/accessories on AIU #1. I can program AIUs 2-4, but they do not operate. I saw it was a firmware issue that needed to be upgraded.

I'm just surmising, but I believe the android software needs more work on it to work properly. GunrunnerJohn felt there would be plenty of issues when you tried to match 2 different operating systems (MTH/Android) to run smothly. Before WIFI, we had the TIU matched to an MTH remote that was made to work with one another.

I am so thankful for the OG forum!! With it, I have been able to find answers to my problems 95% of the time by just using a search. This forum literally taught me the DCS system. We are so very fortunate to have this

Update! I switched operations to my iPhone 15 Pro Max and everything works nearly flawlessly using my home network. I was using a cheap $50 Onn tablet before. It does seem that some operating systems/devices play better with the WTIU than others.

You're the second person to report problems with the 7" Onn tablet and the app. I have used the older 2023 model of this tablet and the app with no problems. I'm considering picking up the newest model just test it out.

Well I suppose I am relieved the issue lies within the $50 tablet instead of the $400 WTIU! 😀

Happy New Year!

After powering up the WTIU twice this morning, I had intermittent power issues to the track. Please see the video in this post of the WTIU continuously resetting itself. I have an MTH power brick going into each of the fixed channels. The first time I attributed the issue to a possible short in an Atlas Deluxe cab car. Then after removing the cab car, shutting the WTIU down for a few mins and powering up an again, I had power to the tracks as normal. I fired up a Ps2 engine and started running, all of a sudden I could see the Fastrack switch lanterns flickering and the engine shut down. Then the WTIU reset itself, restarted with track power and I have been running trains without issue for the past half hour+. I would think this could be indicative of a short, but the breakers on the MTH power bricks have not tripped at all today. In the past with the regular TIU connected, the breakers would trip immediately during a short, derailment etc. Could it be an issue within the WTIU?

I'm the other person.  Like someone else posted, the app works really well on an older tablet.  In my case a 2017 Samsung SM-350 tablet, but not on the newer ONN 7" tablet.  Everything freezes after loading an engine.  Conversely, the Lionel Base 3 won't work on my older Samsung SM-350, but works flawlessly on the ONN 7" tablet.  So I use one for one and one for the other.

I had similar problems,  and I use an older ipad. I have 16 engines on 3 tracks. It seems to take several refreshes to find all the engines. Once they are all there they run fine but using all engines the sound, bells, smoke, and horn only work individually. The app will not control all at once. Hopefully the next update helps.
