Steps
Confirm there is no official Mitsubishi Electric developer API or program for kumo cloud — all available integrations (pykumo, kumojs) are community reverse-engineered.
If proceeding, use a community library such as pykumo, which talks to the kumo cloud device's LOCAL network API (not a Mitsubishi public cloud endpoint).
Derive the per-device security token by replaying the same account/pairing handshake the kumo cloud mobile app uses, as documented informally by the pykumo/kumojs maintainers.
Poll or set mode, setpoint, and fan speed via the local HTTP endpoint once the token is obtained, requiring your integration to have network access to the customer's kumo Cloud gateway device.
Treat the integration as fragile: Mitsubishi can change the app's pairing protocol or add local-API protections at any time without notice, since none of this is a published interface.
Known gotchas
Honest negative: there is no supported, documented Mitsubishi API to build a commercial product on — everything here is unofficial and reverse-engineered.
The working 'API' is local-network based (talks directly to the indoor/gateway unit on the customer's LAN), not a public cloud REST API.
Expect breakage on Mitsubishi app or firmware updates with no changelog, deprecation notice, or support channel.
