Unable to connect UI

[Ohad]

After almost a year with a working system, I suddenly can’t log in into the UI, not trough the Android app nor through the web browser.

With the Android app, I get the “Unable to connect to Home” message.
With the browser (Firefox or Chromium), I can see the login page but when I push the Submit button it’s loading for a half-second and then the page refreshes and I got the login page again.

Strangely, the REST API works, and I can get and set info through it (with the MD5 of the password). http://local-ip/su also works.

I have tried to restart the device, my router, and my modem, nothing helps.

Any ideas? What is wrong or what can I do?
Thanks,
Ohad

What’s the hardware version? And do you know what firmware runs on it?

[Ohad]

I have the AC powered OS3.0.
Actually, after I posted yesterday, I successfully update the firmware to 219_rev3 (it was rev2 before).
It didn’t solve the problem.

One thing you can check is open a browser and type in the following:
http://x.x.x.x/ja?pw=yyyy
where x.x.x.x is your controller’s IP address, and yyyy is the md5 hash of your device password (you can use https://www.md5hashgenerator.com/ to generate md5 hash from your password).

This should return controller settings in json format. One possibility is that the json string is corrupted, like there are garbage characters in the string. You can copy the entire string and paste it to a json parser (such as http://json.parser.online.fr/) to check its validity.

If indeed the string is corrupted, you can perform a factory reset. But I do suggest you keep a copy of the output of the /ja command above, as that will help recover the settings after the factory reset.

OK, I fixed it 🙂
I deleted the corrupted programs with /dp and it all works now!

Do you have any idea how it could have happened and how I can avoid it in the future?

Thanks a lot!

(I posted this before and it deleted some how)

WOW. It seems to be the case!

That is the JSON:

{"settings":{"devt":1590013997,"nbrd":1,"en":1,"sn1":0,"sn2":0,"rd":0,"rdst":0,"sunrise":342,"sunset":1174,"eip":1599502721,"lwc":1590008749,"lswc":1590008749,"lupt":1589935790,"lrbtc":7,"lrun":[3,3,1200,1590006001],"RSSI":-65,"loc":"31.53830,34.91192","jsp":"https://ui.opensprinkler.com/js","wsp":"weather.opensprinkler.com","wto":{},"ifkey":"","wtdata":{"wp":"Manual"},"wterr":0,"curr":0,"sbits":[0,0],"ps":[[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0]]},"programs":{"nprogs":3,"nboards":1,"mnp":40,"mnst":4,"pnsize":32,"pd":[[1,127,0,[480,0,0,0],[0,0,600,0,0,2400,900,0],"בוקר"],[49,0,2,[1080,0,0,0],[0,0,0,0,0,0,3600,0],"עצים "],[1,127,0,[1200,0,0,0],[0,0,0,1200,0,0,0,0],"עציצ"]]},"options":{"fwv":219,"tz":60,"ntp":1,"dhcp":1,"ip1":192,"ip2":168,"ip3":1,"ip4":7,"gw1":192,"gw2":168,"gw3":1,"gw4":1,"hp0":80,"hp1":0,"hwv":32,"ext":0,"sdt":0,"mas":1,"mton":10,"mtof":-10,"wl":100,"den":1,"ipas":0,"devid":0,"uwt":0,"ntp1":50,"ntp2":97,"ntp3":210,"ntp4":169,"lg":1,"mas2":0,"mton2":0,"mtof2":0,"fwm":3,"fpr0":100,"fpr1":0,"re":0,"dns1":192,"dns2":168,"dns3":1,"dns4":1,"sar":0,"ife":0,"sn1t":0,"sn1o":1,"sn2t":0,"sn2o":0,"sn1on":0,"sn1of":0,"sn2on":0,"sn2of":0,"subn1":255,"subn2":255,"subn3":255,"subn4":0,"wimod":42,"reset":0,"dexp":0,"mexp":8,"hwt":172},"status":{"sn":[0,0,0,0,0,0,0,0],"nstations":8},"stations":{"masop":[254],"masop2":[0],"ignore_rain":[0],"ignore_sn1":[0],"ignore_sn2":[0],"stn_dis":[146],"stn_seq":[254],"stn_spe":[0],"snames":["ראשי","מים אפורים","המטרה","מרפסות","רזרבה","טפטוף","עצים","S08"],"maxlen":32}}

And I got the error:
SyntaxError: JSON.parse: bad control character in string literal at line 1 column 651 of the JSON data

Can I override this JSON somehow?

Thanks for the help!

Good to hear. I am not sure about the cause of the corruption. It’s possible that it got corrupted during a writing event to the flash memory. Generally a factory reset will wipe out the flash and get rid of the corrupted data. Therefore I would recommend saving a copy of the configurations every time you make changes, so that in the rare event this happens again, you can perform a factory reset and recover the configurations easily.

I always seem to have a recurring issue where the UI goes blank screen on me .. for some reason I thought this was related to the weather adjustments historically, but not sure.

I’ve recently upgraded to latest firmware, but it seems every morning the screen goes back to blank.

When I do the json check with http://<ip>/ja?pw=<md5&gt;

I only get the following
{"fwv":219}

only a reboot of the OS fixes it .. any thoughts? was this the problem you were having?

I’m having a similar issue…. URGENT….

I was trying to copy programs to clean up the zones on my computer (some zone programs were out of place and cant move them?)

anyways, now I cant login to the app or ip on same wifi… it recognizes when i put in the wrong login password and acts like its going to log in but it just stays on the login screen…

on the app it says unable to connect. its not a wifi issue (orbi thats been working for a while)

any help? PLEASEeeeeeee

thanks!!
Jim
