Weishaupt WEM Portal tools (8, 1 write)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • wem_get_device_status

    Get connection/online status of a specific device.

  • wem_get_devices

    Get all WEM devices with their modules. Returns device IDs, names, connection status, and module list (each with Index, Type, Name). Use this first to discover deviceId, moduleIndex, and moduleType needed for other tools.

  • wem_get_overview

    Get a complete overview of a device: all modules with all their parameters and current values in a single call. Useful for getting a full picture of the heating system state.

  • wem_get_parameter_meta

    Get metadata for all parameters of a module: parameter IDs, names, writable flag, data types, min/max values, enum options. Use this to discover available parameters before reading values.

  • wem_get_parameters

    Get all parameters of a module with current values. Combines metadata + refresh + read into one call. Returns parameter names, current numeric/string values, units, and writable flags.

  • wem_get_writable_parameters

    Get only the writable parameters of a module (parameters that can be changed). Shows current values, min/max ranges, and enum options. Useful to see what can be adjusted.

  • wem_read_parameters

    Read current values for specific parameters. Refreshes data from device first, then reads. Use when you only need specific parameter values instead of all.

  • wem_write_parameterwrite action

    Set a parameter value (e.g., target temperature). Only works for writable parameters. Check wem_get_parameter_meta for min/max values and enum options first.
