| 1. Handheld single point meter reading | YL-801UG supports single point meter reading and can independently read data for each form without networking. Integrate a YL-800T module (version 2.7 or above) into the handheld device, set the module as the central module, and ensure that the parameters are consistent with the table parameters. Send data according to the protocol for meter reading and control. |
| 2. Concentrator remote meter reading | Concentrator meter reading can use 3G/4G and small wireless low-power MAC networks for remote meter reading. Before the first meter reading, it is best to set up a network for the concentrator, which takes time. After the network is completed and a routing table is established, the remote server can obtain the number of nodes and network paths. Wireless meter reading can also be performed. If a small number of meters do not have a network path, meter reading can be performed, but it will force them to find a path. |
| 3. Hybrid meter reading with concentrator and handheld device | The YL-801UG protocol supports both single point and network commands, so mixed meter reading can also be implemented, making it convenient to use a handheld device for meter reading even when there is no network. |
