If you experience errors during the boot of HA regarding the connection to the Bosch cloud ie Timeout while connecting to Bosch cloud. Retrying in the background, you may want to change the OpenSSL configuration.
The OpenSSL defaults for Buster are causing the problem, probably because Nefit/Bosch is using either an outdated TLS version or an outdated cipher.
Edit /etc/ssl/openssl.cnf and change the system wide defaults back to their previous values(pre-Buster):
MinProtocol = None
CipherString = DEFAULT
