What it can read¶

Each getter sends one SRM call and returns its answer as a typed model. Field names are SRM's own keys in snake_case, including SRM's spelling (is_baned), so SRM's documentation and the web interface's requests map 1:1. Values keep SRM's units and formats; raw holds the complete object.

Method	SRM API	Returns
`get_system_info()`	`SYNO.Core.System`	model, firmware, CPU, RAM, uptime, clock, USB devices
`get_utilization()`	`SYNO.Core.System.Utilization`	CPU and memory load, traffic per interface
`get_network_devices()`	`SYNO.Core.Network.NSM.Device`	every known client: online state, addresses, Wi-Fi band and signal
`get_topology()`	`SYNO.Core.Network.Router.Topology`	router or standalone access point
`get_connection_status()`	`SYNO.Core.Network.Router.ConnectionStatus`	WAN state and the WAN interface's own address, live
`get_external_ip()`	`SYNO.Core.DDNS.ExtIP`	the addresses the internet sees, as SRM last recorded them
`get_ipv6_prefixes()`	`SYNO.Core.Network.IPv6.Router.Prefix`	delegated prefixes and the local network using each
`get_dhcp_servers()`	`SYNO.Core.Network.DHCPServer`	DHCP ranges, gateway, DNS, lease time per local network
`get_dhcp_clients()`	`SYNO.Core.Network.DHCPServer.ClientList`	handed-out addresses with remaining lease time
`get_dhcp_reservations()`	`SYNO.Core.Network.DHCPServer.Reservation`	fixed address assignments
`get_firewall_rules()`	`SYNO.Core.Security.Firewall.Rules`	default policies and the rule list
`get_firewall_hit_counts()`	`SYNO.Core.Security.Firewall.Rules.HitCount`	packet counters per kernel rule
`get_forward_rules()`	`SYNO.Core.Security.Firewall.Forward.Rules`	firewall openings for port forwards, DMZ, UPnP
`get_port_forwards()`	`SYNO.Core.Network.Router.PortForward`	port forwards, including UPnP
`get_port_triggers()`	`SYNO.Core.Network.Router.PortTrigger`	port triggering rules
`get_allow_srm_from_wan()`	`SYNO.Core.Security.Firewall.AllowSrmFromWan`	whether SRM itself is reachable from the internet
`get_firewall_conf()`	`SYNO.Core.Security.Firewall.Conf`	general firewall settings
`get_forward_conf()`	`SYNO.Core.Security.Firewall.Forward.Conf`	automatic openings for port forwards, DMZ, UPnP
`get_auto_block()`	`SYNO.Core.Security.AutoBlock`	blocking after failed logins
`get_wifi_radio_settings()`	`SYNO.Wifi.Radio.Setting`	channel (0 = automatic), width, power per radio
`get_wifi_radio_status()`	`SYNO.Wifi.Radio.Status`	channel in use and BSSID per radio
`get_wifi_devices()`	`SYNO.Wifi.Device`	signal, link rate, connection time, traffic of each Wi-Fi client
`get_eth_port_info()`	`SYNO.Mesh.Network.EthPortInfo`	link state and speed of every Ethernet port
`get_mesh_nodes()`	`SYNO.Mesh.Node.List`	the router and its mesh points
`get_usb_volumes()`	`SYNO.Core.Storage.Volume`	USB storage: file system, size, free space

Anything derived is in aiosynologysrm.helpers, kept apart from the models on purpose: locate_clients() tells for each client which router or access point it is attached to, by Wi-Fi (which radio) or cable, from the lists of several devices; the classification of an address (address_scope: public, private, carrier-grade NAT), summed hit counters per rule (hits_by_rule), radio settings paired with their live state (pair_radios), durations and dates from SRM's text (up_time, lease_remaining, firmware_date), used space, and config_hash() to detect configuration changes from the models' raw.
