Hi All,
I have trouble setting up the right logging method for my smart gas meter. The meter itself is read by a box that produces an xml with an ever incrementing value for the cubic metres used.
The set-up I have now is like this (see attachment)
- Total pulse count to pulse increment
- Log to feed
- kWh to kWh/d
But that does not produce the correct feed data for hourly and daily usage. Can anyone show me a screen dump of their setting in emoncms?
Re: Logging accumulating Gas usage
I don't log gas use so don't have a screenshot for you, but I expect you need to convert the m³ into kwh using the calorific value (found on the bill or website). once you have an ever increasing energy value in kwh's you can use "kwh to kwh/d" for daily total and "kwh to power" for a current rate of use in kw's . something like

Hi Paul,
That did not work out for me. Let me try to explain a bit better.
I had a input that reads the total use of m3 gas every hour, as an two decimal value, like this:
11:50:19 258.79
10:49:29 258,13
09:50:38 257,29
08:49:48 257,29
This is an ever increasing value. Now I want to log the difference every hour, so I can visualize the hourly use, and make also an feed for the daily use. The main objective is show the data in the zoom visualization, so I can see the associated costs.
I tried some input processors already, but I did not get the expected feed values.
Re: Logging accumulating Gas usage
Hello,
I would like made the same think. I have draw a little image. For this moment, I don't have found the good method. In this picture, it's not in minute or hours, but if you can made for a hours, I think it's the same idea.
If it's not possible to do that, maybe I can write this function. I have already look the php code and I think it's not a big job to add this function.
Best regards
