Simple example of Ecowater Water softener REST API client written in JS for NodeJS. Tested with eVOLUTION 200 Compact. May work well with other devices with slight modifications. Check remarks.
App requires NodeJS >= 13 (tested with 16.2.0).
yarn install
Set ECOWATER_EMAIL, ECOWATER_PASSWORD, ECOWATER_DEVICE in .env file (copy sample.env as template) according to your account at https://wifi.ecowater.com.
ECOWATER_DEVICE is the Device Serial Number (DSN) without #.
Run yarn start to fetch device statistics.
Run yarn regenerate to force resin regeneration.
Some values are calculated based on device properties that are loaded the first time you use the application from the zip file. One example is salt level which is calculated by: value*100/max.
Max value can be obtained from device properties file: https://wifi.ecowater.com/api/yml?version=0 (99602.yml).
By default, I assumed max = 50 which is fine for eVOLUTION 200 Compact, but you probably should change that to fit your device.
