Problem retrieving devices! after enabling python plugin

[lrybak]

I have problem with one of my plugin (https://github.com/lrybak/domoticz-storm-report).
A while after enabling my plugin, Devices section won't load - Problem retrieving devices! alert message appears
The Devices sections doesn't load becouse of the problem with JSON parsing
I found that for some reason, after enabling my plugin some other devices (wunderground idx 168 and 169) are being changed.
After that JSON for Device section is malformed and refuse to load (/json.htm?type=devices&displayhidden=1&displaydisabled=1&filter=all&used=all)

Please see step I performed to reproduce this issue

I used v3.8564 but the issue exists on stable v3.8153 as well

Hardware view


Section Devices display correctly


Data in DeviceStatus table (idx 168 and 169)


Enable my plugin + domoticz restart


Hardware view - plugin enabled


Device view - Problem retrieving devices!


Bad formated float value in json (/json.htm?type=devices&displayhidden=1&displaydisabled=1&filter=all&used=all)



Data in DeviceStatus table (idx 168 and 169) changed


Hardware table


I disabled plugin and did domoticz restart
sqlite> Update Hardware set Enabled=0 where Extra='domoticz-storm-report';
After a while Devices sections has appeared again


Data in DeviceStatus table (idx 168 and 169) changed again to correct values
Everything is working correctly


My plugin has nothing to do with the idx 168 and 169 devices.
Do you know what is the reason of such situation?


Edit:

I enabled verbose logging and found that a while after enabling my plugin the problematic device were updated (float value with comma and not with dot) causing JSON parse error and prevent Device page to load

Strange, isn't?

I solved my issue. There was a problem with gettext module used. The problem has gone once I removed gettext based translations
