Hi, I have tried to search before posting but could not find a “best pratice” for this question. I have 22 meeters that are just sending the kwh from 0 - 65565 (or something around that) I want to use this to generate 4 items - ItemDaily, ItemWeekly, ItemMonthly, ItemYearly. I want to show on ha…

Thanks for all the input. My solution ended up with this rule, this way i get the energy comsumption today(updating at every change), yesterday, week, month and year. I think the information you get from one sensor makes it valuable with this rule. Hope this can be usefull for someone else. rule "…

[image] tomhag: My question is how is the best way to do this? With .rules or rule generator? I don’t know what you mean with “rule generator”. But yes, you will want to use Rules and Persistence. [image] tomhag: Can i make a more global rule? What do you mean by “global”? Most peopl…

This seems very nice, i will have to look in to it. Does the database use alot of ressources and MB? Is it easy to set up?

Sorry about my words, i ment rules in paper UI. With the word global i ment that maybe it was possible to make one rule and tag alot of items? Instead making one rule per item? About the rule, that seems like a good solution, but i still need to make one rule per item/meeter?

My RaspberryPi 3B can handle it pretty well. I had no problems so far.

There are a number of ways to make generic rules. Look Kat the design pattern postings, particularly the separation of behaviors, working with groups in rules, and associated items.

Hi again Rich, I have tried to copy your rule completely, just different names. Could you please verify that it looks ok? Because i get error missing ( and others. Also how would you add the logic for Switch on/off for reset every night? I see that my device do have this feature. I do have other…

[image] tomhag: Could you please verify that it looks ok? I could if you post what you have exactly. Use code fences: ``` code goes here ``` [image] tomhag: Because i get error missing ( and others. Errors in openhab.log or elsewhere? [image] tomhag: Also how would you add the l…

[image] rlkoshak: I mean if the meeter goes from 0-65556. In my mind it would be some kind of logic as with the week? (now-MinusDay(1))? I don’t understand the question. The items that i want to make a rule like this does not support reset, so it will continue to count to 65556, then it wil…

Why not InfluxDB with grafana?

You will not need extra items like this…
