curl set power with errors

[reset12]

Hello,
i like to set set power of my hms-2000 but i get a syntax-error on the curl command as documented.
When i change all blanks to %20 the syntax-error is gone, but the power does not change (this can be a bug reported in issues). I use v23.12.19.

Script(every cmd one line):
#!/bin/bash

write pv-power schuppen in %

if [ -z ${DEBUG} ]
then
#curl --silent --output -u "admin:openDTU42" http://192.168.178.22/api/limit/config%20.-d%20.'data={"serial":"1164xxxxxxxx","limit_type":1,"limit_value":$1}'{"type":"success","message":"Settings%20.saved!"} >/dev/null
#curl -u "admin:openDTU42" http://192.168.178.22/api/limit/config%20.-d%20.'data={"serial":"1164xxxxxxxx","limit_type":1,"limit_value":$1}'{"type":"success","message":"Settings%20.saved!"} >/dev/null
curl -u "admin:openDTU42" http://192.168.178.22/api/limit/config .-d .'data={"serial":"1164xxxxxxxx","limit_type":1,"limit_value":$1}'{"type":"success","message":"Settings .saved!"} >/dev/null
fi

My SUN-2000 Inverter is broken (AC-shortage after 3 month of operation) after a grid outage. The chinese seller from aliexpress fooled me the hole time, and will not send a spare inverter. Now i will change to my HMS-2000 with opendtu to regulate the feeding power from my battery. My hole installation is controlled by a python program and all connected devices are controlled by bash-script. The reason is, i can change from SUN-2000 to HMS-2000 only with a change of the bash script for read/write Inverterb1 as example.

I'm a bit confused if you actually know how curl works. Nevertheless I'd recommend to gather some basic bash or command line usage knowledge beforehand.

Your script can just contain something like:

#!/bin/bash
curl -u "admin:password" http://192.168.178.165/api/limit/config -d 'data={"serial":"1141xxxxxx", "limit_type":1, "limit_value":50}'

The percent escapes in the JSON aren't necessary, also there are dots (.) between some of the parameters which aren't necessary. You also copied the response you get when successfully executing the command from the documentation: {"type":"success","message":"Settings .saved!"} - This can be removed.

I tested my example and verified via the web interface, everything is working perfectly fine.

Also --silent together with --output piped to /dev/null doesn't make any sense, you should decide to use one of the options.

Thank you for the hint, it works now.
