Hitachi Hi Kumo

Hi Kumo is Hitachi's European app for air-to-air heat pumps, and it runs on the Overkiz platform rather than on Hitachi's own cloud. Each indoor unit gets a Wi-Fi adapter, the app pairs up to ten of them, and Home Assistant reaches the same units through the Overkiz integration with Hitachi Hi Kumo selected as the server. That turns a split system with nothing but an infrared handset into climate entities an automation can act on.

Hardware availability

Hi Kumo is cloud only in Home Assistant, and climate entities are the part of Overkiz that the local API does not carry anyway, so a Hitachi install is dependent on the Overkiz cloud by design. Hitachi’s newer residential ranges ship with airCloud rather than Hi Kumo, on the newer SPX-WFG02 adapter instead of the SPX-WFG01, and airCloud is not an Overkiz platform, so check the adapter model and which app a unit was commissioned on before assuming this integration covers it.

Hi Kumo Wi-Fi adapter (SPX-WFG01)

The SPX-WFG01 adapter is what puts a Hitachi air-to-air heat pump on the Hi Kumo platform. One adapter goes into each indoor unit, the Hi Kumo app pairs up to ten of them, and Home Assistant reads the same units as climate entities through the Overkiz integration. Its replacement, the SPX-WFG02, is an airCloud Home adapter and does not reach Home Assistant this way.
