I’ve got a running setup of 9.7.9. I can import Data into that installation’s feed’s, but I can’t calculate “Rate of Change” and “kwh to Power”:
Process ´15´ not available. Redis not installed
But according to php-info redis is active…
And the feed is definitly filled with my imported value’s:
How did I fix it:
$redis_enabled = true;
in settings.php helps a lot!
