convert json to dmp doesn't find json file

mapausch commented 1 year ago

Describe the bug

Trying to convert a json file to dmp file does not work.

Having this files/directories:

[myuser@myhost tasmota]$ pwd
/home/myuser/tasmota

[myuser@myhost tasmota]$ ls -la
insgesamt 308
drwxr-xr-x   3 myuser myuser   4096 19. Jun 22:26 .

-rw-r--r--   1 myuser myuser 223607 19. Jun 21:33 decode-config_v12.5.0.tar.gz

Config_kaffee_12.5.0.dmp is a configuration backup made via Tasmota WebUI. Config_kaffee_12.5.0.json is the converted/decoded dmp file

Config_newdev_12.5.0.json is a copy of Config_kaffee_12.5.0.json, but with other hostname.

Now I try to convert the Config_newdev_12.5.0.json to a dmp file that I could import/restore to a new Tasmota device. But none of the tested methods works:

[myuser@myhost tasmota]$ decode-config-12.5.0/decode-config.py -s Config_newdev_12.5.0.json -t dmp -o Config_newdev_12.5.0.dmp

ERROR 3 (@3881): File 'file:///home/myuser/tasmota/Config_newdev_12.5.0.json' not found

To Reproduce

download https://github.com/tasmota/decode-config/archive/refs/tags/v12.5.0.tar.gz and extract
create dmp file from Tasmota 12.5.0 WebUI and convert it to json
try to create a dmp file from the json file (examples see above)

Expected behavior

json file should be converted to a dmp file

-s, --source <filename|host|url>
                        source used for the Tasmota configuration (default: None). Specify source type, path, file, user,
                        password, hostname, port and topic at once as an URL. The URL must be in the form
                        'scheme://[username[:password]@]host[:port][/topic]|pathfile'where scheme is 'file' for a tasmota binary
                        config file, 'http' for a Tasmota HTTP web connection and 'mqtt(s)' for Tasmota MQTT transport ('mqtts'
                        uses a TLS connection to MQTT server)

the point is the sentence part "'file' for a tasmota binary config file", see also left side "Source" in overview diagram on README - you can't use a json as source.

I do not see the benefit converting a json into a dmp.

For full explanation:

you can simply use the edited json direclty as restore file for the newly device: -s http://newtasmota -i Config_newdev_12.5.0.json
if you want to take your cumbersome way via json -> dmp -> GUI Restore: copy your Config_kaffee_12.5.0.dmp to Config_newdev_12.5.0.dmp and use this as source: -s Config_newdev_12.5.0.dmp -i Config_newdev_12.5.0.json - finally use your GUI and restore Config_newdev_12.5.0.dmp

first is the prefered way

Thanks a lot for your efforts and clarifications, @curzon01 Somehow I didn't realize, that it's possible to restore the json file straight to the Tasmota device :-/ Works like a charm :-)
