Zoho IoT Homepage : zoho.com/iot - Accessing this URL will display the home page of the Zoho IoT Product.
Zoho IoT Application's Homepage: iot.zoho.com/ - Accessing this URL will display the default Zoho IoT application or portal whichever is set as default.
2. Can I configure my own domain's URL (e.g. dgmonitoring.zylker.com) for accessing my application instead of Zoho IoT Application's Homepage link (iot.zoho.com/)?
Zoho IoT Application's Homepage is accessed using the URL - iot.zoho.com/. Instead you can configure your own domain URL using the Custom Domain feature available in the application.
4. If I am a partner handling different companies, how do I customize the portal and configure applications?
Zylker is the Solar Panel Partner, who is handling two Solar Panel Monitoring companies Company Solar_A and Company Solar_B. Here Zylker can create two applications for each company to monitor and manage them.
