6.7 HTTPS certificate generation and renewal HTTPS clients rely on certificates to ensure the server's identity. Operating as an HTTPS server, the V222 is capable of generating self-signed certificates or obtaining certificates from third parties, such as certificate authorities (CAs).
Page 20 HTTPS certificate settings Identity of the server is protected by a private key, which must be kept secret. V222 currently supports RSA private keys only; the number of bits can be configured. A key is generated by default; you can create a new one by pressing the "Generate"...
Page 21 Unlike the key, a certificate is public, not secret, and assures that its holder indeed is the entity it claims to be as long as the client trusts the certificate's issuer. To configure what your V222 claims to be, the following certificate signing request (CSR) fields need to be filled: •...

Let's Encrypt, Buypass, ZeroSSL and others. The current implementation only supports the http-01 challenge, so the V222 (or the network it is on) needs to be configured so that HTTP requests to the names and addresses specified and port 80 are routed to the unit's HTTP port.

Page 69 10.11 SNMP sample commands These examples assume you have your V222 at 192.168.0.100 with SNMPv3 user configured with powerAdmin SHA1 for authentication and AES for encryption, with password powerAdminPassword for both authentication and encryption. Requests with the private community string are assumed to be serviced as though they were made by the user.
Page 70 General MQTT settings V222 can function as an MQTT client, so you need to have a configured MQTT broker which it could connect to; then, other MQTT clients connected to the same broker could communicate with it (multi-broker configurations are also possible but out of scope of this document).
Page 71 MQTT payload format is not defined by a standard, so we explicitly define it here. Everything that can be controlled via MQTT in V222 is an outlet state, which can be ON or OFF. We encode ON as '1' (the single ASCII character '1') and OFF as '0'.
Page 72 These examples assume you have an MQTT broker at 192.168.0.5, it doesn't require authentication and you have the V222 set up like shown on screenshots above. You'll need the mosquitto MQTT client to run these samples; analogous commands should be available for other clients.
