Entities

Entities

Every entity the integration can create, with the register or web-interface value behind it. A heat pump entry with all five heating circuits switched on creates 214 entities, 22 of them per heating circuit; its web interface entry adds 54. The tables below are generated from a full setup of the integration, so they match the code of the release they were built from.

Which entities your heat pump gets

• Heating circuits 2 to 5 only when switched on in the setup or under Reconfigure (see Installation and Setup). Circuit 1 is always there. A circuit's registers can answer even where the controller has no such circuit (circuits 2-4 on the WBB), with factory values, so the integration compares your choice with the controller's own setup and raises a repair notice where they differ.
• Electrical power (33126) only where the firmware serves the register, decided at the first poll after the integration starts.
• Heating power (the estimated heat output) is calculated from the power map you picked; it reads unknown when the map cannot be loaded (see How Data Updates).
• Any other register range the controller refuses keeps its entities, which read unavailable; only a refused system range (30001-30006) counts as a connection failure.
• Web interface entities exist only with a web interface entry (see Web Interface). They are listed as a WBB has them; the same page says what differs on an Evoblock.

Entities marked disabled by default are created but disabled; enable them on the device page under the disabled entities. Two such registers are in no Weishaupt data-point list: 31106 (per circuit) repeats the circuit's operating mode, and 36801 has no known meaning and reads 0 on the project's WBB.

Reading the tables

• Entity is the name Home Assistant shows in English and, below in italics, in German. The entity ID follows from the device and the English name, for example sensor.wh_system_outside_temperature; a further heat pump's device postfix becomes part of it.
• Register is the Modbus address as Weishaupt's data-point list writes it: 3xxxx input registers, 4xxxx holding registers. Rows without a register are calculated or count something. The full register reference is in Modbus Register Reference (EN).
• Type, values, notes names the type where it is not a plain sensor. sensor (setting, read only) is a register the controller would accept writes to, shown read only to spare its EEPROM.
• The values give the range and step the integration accepts for a number (where checked, the grid of the controller's own menu) and a select's options. The controller may allow less at the moment, for example Automatic and Cooling only with cooling enabled.
• Switch rows belong to a setpoint the controller can switch off: the number reads unknown while the setpoint is off, the switch turns it off and on again and restores the value it held.
