UnhandledPromiseRejectionWarning: Error #12

Hello @lukasroegner,

I noticed recently that Homebridge logs throw this warning repeatedly. The plugin seems to work correctly but I get loads of these error messages.

(node:28533) UnhandledPromiseRejectionWarning: Error: Response Error: 504 Gateway Time-out at internals.Client._shortcut (/homebridge/node_modules/homebridge-tado-smart-thermostat/node_modules/wreck/lib/index.js:635:11) at runMicrotasks (<anonymous>) at processTicksAndRejections (internal/process/task_queues.js:97:5) at Object.request (/homebridge/node_modules/homebridge-tado-smart-thermostat/node_modules/simple-oauth2/lib/core.js:64:20) at AccessToken.refresh (/homebridge/node_modules/homebridge-tado-smart-thermostat/node_modules/simple-oauth2/lib/access-token/index.js:35:24) (node:28533) UnhandledPromiseRejectionWarning: Unhandled promise rejection.

I see this whenever my internet is down. Seems to be a connection problem with the tado server?

Indeed, those errors occur due to the Tado server being down (HTTP status 504). Those errors are not handled by the library the plugin uses to communicate with the API, thus the errors cannot be removed. As they are not causing homebridge to shut down and issues on the Tado server-side should be rare, they can be ignored.
