Launch Espruino Web IDE и and copy all the sketch.js contents. Config the firmware as described below. Delete all the unnecessary comments and upload it to Iskra JS.
Use the table of values at the end of this readme if you have trouble understanding the key-value pairs.
Change your Wi-Fi network settings in SSID и PSWD keys.
Change host, port и path parameters in options to connect to the API server. Use Base64-encoded login and password in Authorization.
Unencoded login and password:
Login:Password
Encoded login and password (Base64):

A list of services that can help to encode in Base64:
Geolocation is set up manually once when setting up the weather station in sensorsData with City and Street parameters. They are automatically replaced with NULL if being omitted.
The weather station sends request once a minute (60000 ms) and redirects received data to API server immidiately. This can be changed in setTimeout which is used twice in firmware code (strings 57 and 110). It’s recommended to use same value in both places.
This table explains what the main variables from sketch.js actually are.
