No devices in status.js when no power is generated

[freddieleeman]

When my inverter (PowerOne + iGEN Wi-Fi external logger) does not generate any power for a while, the inverter disappears from the status.js source, causing errors and resulting in 'Unavailable' sensors.

status.js with sun:

var yz_device_num="1";
var myDeviceArray=new Array();
myDeviceArray[0]="xxxxxx          ,xxxx,,-xxxx-,,xxx,x,xxxxxx,,x,";
;
function initPageText()

status.js without sun:

var yz_device_num="0";
var myDeviceArray=new Array();
;
function initPageText()

Possible fix:
This issue could be resolved by using the cache when the source is retrievable (status.js found), but the regex for the data fails (or yz_device_num value is 0). The power_current sensor could be forced to 0, and the power_today and power_total values could be retrieved from cache.

Is there any way we can help you with this issue? It has been open for a while and in the meantime a lot of work has been done on a v2.0 version of this custom component.

I worked around this issue by using SQL to retrieve the latest valid value, but it would be great if the integration caches the values to avoid 'unknown' status.

Before we can continue we need to make a decision on what to do with unreachable inverters. Feel free to jump in on klaasnicolaas/python-omnikinverter#24 :-)

Created a new issue with more details about this :-)
