Possibility to add entry level kWh.

10 years ago • updated 10 years ago • 2

When uding the Energy Meter from Foogadget, there is a possibility to add the entry point kWh when installing it. It's normally done using the configuration scripts (i.e. TotalEnergi = Start_value + SUM(temp*10)/1000).

My suggestion is that on the settings page for sensors, add the "now" value for the electricity meter on the wall, to get the total consumption according to the electricity commpany rather than accumulated kWh from installation date.

I've been thinking about this. But I decided to only show the current usage over time and not try to calculate the accumulated total. One reason is that Tellmon does not use the backup sensor of the FooGadget meter, only the primary sensor. I can see from the message counter that quite a high number of messages get lost. Loosing reading when only showing the instance usage is no big deal. But trying to total the energy reading it would quite fast end up with a total that did not match the actual total on the real energy meter. I suspect the Telldus/Tellstick is not 100% reliable and that's why the FooGadget meter has a backup reading as well.

Tellmon now has 1709 sensors and 4298 devices connected that it receives values from. It receives about 10 values pr. second. This is handled quite well so far, but if I'm to support the backup sensor of FooGadget I need to do some more calculations and lookup the previous value and message count in order to detect a possible missing reading and then read the backup sensor.

As I don't have a meeter myself the whole thing is a bit difficult to work with. I'll add your suggestion to the whish list, but I can't promise anything.

No problem. I undestand the obstacles. It's a "nice to have" function, but only if it can be trusted.
