unexpected token in JSON

[Ansula1267]

When trying to get information from a CT200 thermostat using
bosch-xmpp easycontrol get /

I get the following error:

SyntaxError: Unexpected token � in JSON at position 0

During installation of bosch-xmpp I got several warnings regarding deprecated packages
npm i -g bosch-xmpp
npm WARN deprecated node-xmpp-client@3.2.0: this package is deprecated please use https://www.npmjs.com/package/@xmpp/client

/usr/bin/bosch-xmpp -> /usr/lib/node_modules/bosch-xmpp/bin/bosch-xmpp

Can the errors be the result of these deprecated packages? If so, how to make sure the correct versions are used? (I have seen the links in the warnings, but I don't know how use/install these.)

I am running a raspberry3 with Linux 11 bullseye, with
node -v
v14.21.3
npm -v
6.14.18

JSON parse errors are caused by using an incorrect password. If you're sure you're using the correct one, sometimes it helps "downgrading" to a more simple password (only letters and numbers) of limited length (8 to 10 characters).

[Ansula1267]

Thanks for your quick reply!
I changed the password to an 8-character string (lowercase, uppercase and digits) but got the same error message.
I assume that the cli parameters --serial and --access-key are for the thermostat device (supplied by the manufacturer) and --password is for the Bosch login (set/changed by me).

[robertklep]

That's correct. The serial number and access key are used to connect to the XMPP server, and the password is used to encrypt/decrypt the data going to/coming from your thermostat.

You can run the CLI tool with debug logging enabled, perhaps that provides a clue why it's not working for you:

$ env DEBUG=* bosch-xmpp easycontrol get /

If you don't want to share the log on a public medium like Github, feel free to e-mail it to me (robert AT klep DOT name).
