-A. Those two sensors read data directly from your service point. The i-de API for this data is **very** unreliable, > 50% of the calls fail. We try out best to circumvent this situation but we can't do magic.

+## Q. Why accumulated (or instant) consumption sensors are only updated once at hour? Can be this interval shorter?
+
+These sensors need to read the service point directly. 
+
+The i-de.es service point API is not very reliable, we try up to three calls before giving up in each update window (interval 50-59 of each hour).
+
+On the other hand, the i-de.es platform blocks users if the service point is queried your user if he queries the service point too often. In our experience, no more than 5-6 calls in 10 minutes.
+
+The policy of updating the sensors only once an hour is given by the sum of these two situations.

 ## Q. Accumulated (or instant) consumption sensor shows 0 increment at some intervals.
 
 A. Readings from this sensors only returns integer values. If from the last reading your meter indicates a variance minor then 1 kWh, the integration will not reflect any variance and that will only be recorded once the variance from the previous reading is greater then 1.
 
-* The "instant" and "accumulated" readings are done directly to your meter. Due to connectivity issues or i-DE server issues, you may not always obtain readings as expected. Keep in mind that sometimes a delay on the reading may occurr.
