Just upgrade from Emoncms v3 to Emoncms v5

My Electric


The new Emoncms v5 is great!

I had a bit of difficult during migration, but after that the result is fine!


This is new Report module of emoncms5 and it’s very helpful !


During migration i wrote some query for check the data integrity:

Extract double records from feed_3 (histogram table):

SELECT * FROM feed_3 as A
FROM feed_3 AS B
WHERE A.time = B.time
AND A.data2 = B.data2
GROUP BY B.time,, B.data2
LIMIT 0 , 30

This query is helpful for check that Report module doesn’t give wrong results.


Extract double records from feed_2 (kwh/d table):

FROM feed_2 AS A
FROM feed_2 AS B
WHERE A.time = B.time
GROUP BY B.time,
LIMIT 0 , 30

Emoncms3 sometimes wrote double records for the same day, this query can show you what days are double.

    I could add to my blog that automatically tweet my newest twitter updates.
    I’ve been looking for a plug-in like this for quite some time and was hoping maybe you would have some experience with something like this. Please let me know if you run into anything. I truly enjoy reading your blog and I look forward to your new updates.

      I execute these commands every 2-3 days and delete records result from them. This keeps my data clean.
