It’s an Amazon Cognito OAuth token so the long way of getting the token from just a username and password is generally going to require some coding. The easier way is to let the web app do it for you by going to https://web.emporiaenergy.com and using your browser’s built in development tools to see the request/response to https://cognito-idp.us-east-2.amazonaws.com/ and pulling the tokens you need from the response data. The token is only valid for an hour so you’d need to call the refresh url every hour to get a new one, there’s sadly not a way to get a static API token for third party purposes like these (yet).

@jj613 Short answer is by monitoring the network traffic of the app. See here for documentation, there might be other documentation out there as well that is more/less featured. https://github.com/magico13/PyEmVue/blob/master/api_docs.md

Without pulling the private keys off the current firmware you’re not going to be able to MITM it, unless you’ve got a way to decrypt https traffic without the keys, so overwriting the current firmware should the cloud site go down is probably easier. Anyway this is getting off-topic enough that it should either be a different thread or otherwise discussed elsewhere.

I’m pretty sure the hardware is all ESP-32 based so someone could in theory write a custom firmware for it to all be local but it obviously wouldn’t work anymore with their app and cloud.

For those of you looking for home assistant integration, there’s always this project https://github.com/magico13/ha-emporia-vue and for those who want to put data into InfluxDB there’s this https://github.com/jertel/vuegraf
