Hi everyone! 
After OCEA, the other big name in shared property meters: here comes ista Web’conso, your ista readings in Gladys, for properties managed by ista in France (the portal https://www.ista-webconso.fr).
What it does
Your heating cost allocators, one per radiator, with their index, plus the day’s heating units, weighted by the coefficient of each radiator as on your statement. These are not kWh: these units tell you what part of the building’s heating bill you are responsible for, and the integration displays them as such.
Your cold water and hot water meters, in m³, with a total per fluid when there are multiple meters.
Readings on the right date: the portal sometimes publishes with a few days’ delay, and each reading is stored on its actual day in the graphs.
A « ista Consumption » widget.- In French, English, German, and Spanish
Installation

It will be available in the store later today. In a hurry? Integrations → Install from GitHub, with the address GitHub - guim31/gladys-ista: ista France (ista-webconso.fr) water and heating consumption for Gladys Assistant · GitHub
- In the configuration, enter the email and password of your ista Web’conso resident space.
- Click on Test connection and read now.
- Discovery tab: add your property.
If the password connection ever fails, there is a plan B, described step by step in the documentation: paste the session cookie from your browser.
Readings are taken every 12 hours by default, to spare the portal.
Honest small reservations
- Beta, developed without an ista account. I checked the connection against the real portal: it goes through ista’s login page, without a captcha, and correctly identifies a wrong password. What remains to be seen on a real account is the reading of the meters, especially for water.
- It’s the most fragile of my integrations: ista has no public API, and the integration reads the portal like your browser.
- It’s the French portal. In Germany, ista uses EcoTrend, another service.
If you are with ista in France, your feedback is very welcome 
@Jluc, if you also have ista somewhere, don’t hesitate!
