Maybe a nice add-on would be a kind of alerting based on fe tresholds. Ideal would be sms based.
I'm thinking about alerts in case of:
1. More then 10.000W usuage of electricity
2. Double intake of gas consumption
3. More then 120 liter on minutes
With this, people could trigger alerts for their needs. I'm personally intrested in the last one. Last time, we had a water valve that was broken. Luckly we were at home. But what if we were not? 1000 of liters could been spoiled...
