WeHeat Proxy

Proxy to use a single call with a refresh token, for use with Home Assistant.

Archived. Steps to include directly in HomeAssistant

Use either of these secrets. You can generate a refresh token with php auth.php and make sure it includes the offline scope. Otherwise use your credentials.

weheat_token_payload: "grant_type=refresh_token&client_id=WeheatCommunityAPI&refresh_token=ey...."

weheat_token_payload: "grant_type=password&client_id=WeheatCommunityAPI&scope=openid&username=email@example.com&password=YOURPASSWORD"

Now add the sensors to the Rest Platform. Replace the heatpump ID with your own Heatpump ID (from auth.php or as seen in the URL from the portal)

This will fail the first time because it doesn't have a token, but should fix itself after the scan_interval when called again.

Install

composer install

Get the token and heatpump ID

php auth.php

You can request a regular or token without expiration (offline). For HomeAssistant, use offline.

You can get the Heatpump ID from the URL in the portal, or get the data from the API when requested.

Usage

Configure your webbrowser to point all requests to /public and make your calls to your app, instead of the WeHeat API. Or call the API path after index.php, eg.

GET http://example.com/index.php/api/v1/heat-pumps

Your can provide your username/password as Basic Auth, or just the refresh_token as username in basic auth. You can also set the X-Refresh-Token header.

Examples

/api/v1/heat-pumps
/api/v1/heat-pumps/{heatpumpId}
/api/v1/heat-pumps/{heatpumpId}/logs
/api/v1/heat-pumps/{heatpumpId}/logs/raw
/api/v1/heat-pumps/{heatpumpId}/logs/latest

For logs, the following parameters are required in the query string:

startTime (UTC, format yyyy-MM-dd HH:mm:ss) endTime (UTC, format yyyy-MM-dd HH:mm:ss) interval (Minute, FiveMinute, FifteenMinute, Hour, Day, Week, Month, Year, with max duration: 2 days, 1 week, 1 month, 1 month, 1 year, 2 years, 5 years, 100 years)

Fields

status: 40 = Standy, 70 = Heating, 90 = Defrost, 130 = Cooling, 150 = DHW, 160 = Legionella, 170 = Selftest, 180 = ManualControl

Example HomeAssistant

In secrets.yaml add the refresh token (from auth.php).

weheat_refresh_token: "<your token>""

In configuration.yaml add a Rest sensor.
