MINOR auto-update in Australia stuck in restart cycle - resolving

On June 13 at about 13:00 UTC, MINOR auto-update was changed to the latest solid release 02_05_09. There is an ongoing problem in Australia where the download of a 800K+ release file takes longer than 20 seconds,causing a restart condition in IoTaWatt units running on releases before 02_05_09. I estimate, based on server request volume, that there about 20 units in Australia afflicted with this condition. There are possibly a handful of units in Finland as well.

IoTaWatt.com uses cloudflare to cache the release files globally. There are seven servers in Australia. I have no idea why these 20 or so sites don’t get faster access, as the rest of the world does. Possibly one or more ISP isn’t using the cloudflare presence and is going back to the IoTaWatt.com server in the USA. But that doesn’t explain why thousands of requests fail and zero succeed. My suspicion is that there is some explicit delay being introduced, or a link to the USA is via satellite.

Whatever the cause, to get past this, the auto-update must be stopped and a manual update performed. To stop the auto-update restart cycle, there are three possible approaches:

  1. Try to run the config app repeatedly to catch a window between restarts and set auto-update to NONE. Some folks have had success with this and it should work with persistence.

  2. If you can disable internet from your WiFi router, the restarts should stop long enough for you to set auto-update to NONE, then you can reconnect internet access.

  3. Power down the IoTaWatt, carefully remove the SDcard, mount in another computer, edit the config.txt file changing the line:
    "update": "MINOR",
    "update": "NONE",
    Replace the SDcard and restart.

Once restarted, download the new release file to your computer with the URL https://iotawatt.com/firmware/bin/02_05_09.bin. Select save the file if asked.

Run the IoTaWatt file manager and upload the release file to the download directory


Now send an update command to the IoTaWatt to install the release:


Your system should update and restart.

Given all that is successful, you could hel;p resolve this by posting that you had the problem, your location, who your ISP is and a tracert to iotawatt.com. With enough responses, I might be able to figure out the exact cause.

I am also willing to accept a return for service if you cannot make the above work for you, but time and postage to the USA from Australia makes that a last resort.

UPDATE: 6/20/2020 Estimate that there are about 5 units still experiencing this. A few have documented using the manual update, and the rest have probably finally succeeded in downloading the update. Hopefully this will eventually resolve completely on its own.

UPDATE: 6/24/2020 It appears, from the download statistics, that most of the units affected by this issue have resolved, presumably by eventually downloading the release within the 30 second time constraint. The next hurdle is to update the MAJOR auto-updates. I don’t anticipate as many units affected in Australia, and as with the MINOR update, the rest of the world should upgrade without incident.

I updated my IoTaWatt on 16 June by manually changing Auto-update from NONE to MINOR. All went fine.

My IoTaWatt has been set to MAJOR for many months and is currently running 02_05_02. I switched the update class to MINOR via the UI and got the following:

6/16/20 22:19:44z Updater: Auto-update class changed to MINOR
6/16/20 22:19:46z Updater: Auto-update is current for class MINOR.

Restarted to be sure and got the same output again. Doesn’t look like I’m being offered the update?

Here’s a trace to iotawatt.com from my TPG connection in Brisbane:

Since it looks like I’ll probably be affected by this issue (it has taken multiple attempts in the past to get updates to successfully download), I am changing the update class to NONE for now.

Your update went fine, an dthe tracert looks like you have a solid internet connection.

I’m suspicious of the ADSL. How long does it take to download https://iotawatt.com/firmware/02_05_09.bin? The tracert, if I’m reading it correctly, appears to have a lot of latency.

@jasoncodes - Your connection looks reasonably fast, and I would expect the update to succeed. The reason your unit won’t update when you set MINOR is that I have suppressed MINOR 02_05_02 units from updating due to this problem. If you want to have a go at updating to 02_05_09, just set your auto-update class to ALPHA or BETA. If you don’t want to risk this update problem, you can just use the manual update procedure above, but set your auto-update to NONE before doing so as if you leave it MAJOR, it will immediately revert to 02_05_02, which is the current MAJOR release.

02_05_09 should not have this restart problem.

as bad as ADSL can be, not this time. This report is getting it to my browser but it’s still nowhere near the 20 secs it takes to time out:

I had some spare time again just now to deal with any fallout and tried this update again, this time setting the update class to ALPHA. Looks like as I expected, I was affected. Took a number of tries but it eventually barely succeeded before the watchdog triggered:

Manually updated on 18/6/20 after being unable to access the web interface for a few days.
After killing the WAN connection I was able to set update class to “NONE”, however the Graph+ interface was broken (e.g., appearance similar to unloaded CSS on a web page).

During the udpate period, “power” for three inputs appears to have been recorded as normal, however the kWh accrual for this period has broken (registering about 30% of typical consumption). I’m guessing this is due to being “down for maintenance” repeatedly.

I have manually updated from 02_05_08 to 02_05_09 and all is working now.

Thanks, that’s helpful. Disabling the WAN (internet) is a good way to get a window to set auto-update to NONE. While the WAN is off, it’s expected that Graph+ would not work as it gets a lot of its JavaScript from a CDN on the Internet.

While still only a few samples, a common thread that is emerging is Telstra. That may be because they are ubiquitous in Oz (I don’t know), or it may be they have some type of throttling in place for whatever reason. Worldwide, I am only seeing this problem in Australia.

The problem definitely looks to be high RTT times to iotawatt.com. Some Googling suggests the ESP IP stack has quite a small TCP window (maybe a couple of packets in flight at a time) so high RTT would greatly affect throughput.

Telstra, Optus, and TPG (which includes iiNet, Internode, AAPT, and many more) are the 3 biggest ISPs in Australia. https://lg.telstraglobal.com/, http://looking-glass.optus.net.au/lg/, and http://looking-glass.connect.com.au/lg/ are all showing the same issue.

My work’s Vocus connection shows iotawatt.com going to Victoria and www.cloudflare.com staying local in Brisbane. Looks like lots of less than ideal routing for the IPs serving iotawatt.com. I wonder if there’s just a missing/incorrect BGP rule somewhere.

Buffer space severely limits packet size and flow.

The firmware should be cached on Cloudflare.

Had the same issue, constant red green red led, and restarting.last Monday I ended up pulling the SD card out and placed in PC, I found a thread that suggested deleting the history files based on the Led pattern, I did this and has worked ever since.
Im on 02.05.02, I’m on Major now but I was on minor.
I’m also on Telstra fibre(velocity) at 100Mbps, location Melbourne.

That may not have been the same issue. In any event it’s not the same resolution. Setting to MAJOR only puts off the inevitable. The problem is with 02_05_02, not the new release. Sometime in the not too distant future, MAJOR. will be set to 02_05_09. Right now would be easy for you to set auto-update to NONE and perform the manual update procedure described in the first post of this thread.

Will do. I’ll give it an update in the next few days. Thanks.

After completing all of these steps, I assume we should leave auto-update class set to “NONE” for now?

If you are now on 02_05_09, you can set auto-update to ALPHA, BETA, or MINOR with no problem.
