I found the for-loop in the script that cycles through the data and customized the loop to start at 577 instead of 1, in order to bypass the first two days.
A bit quick and dirty, but it works.

@Willemd, I looked at the thread, but I did not find any information about filtering the last 288 values from the total of 864 values you get from the JSON. Thanks anyway.

Hi,

I need the last 24h to calculate the average temp for the day.
But using JSON as below gives me the last three days (like the graph) but I only want the last day (24h).

Please advise,
Kind regards,
Roel

The two sensors are indeed working. I have collected undecoded ARC for both sensors and contacted RFXcom with the information.

No need to shout. Thank you for your reply, I will contact support at rfxcom.

Updated the firmware of my RFXcom433E to ver1012. The Kerui D026 is now a proper security sensor with three states (normal, alarm and alarm+tamper). Unfortunately only 3 of 5 identical Kerui D026 sensors are successfully added to Domoticz. The other two won't even show up in the RFXcom manager log ...

If you are happy basing your detection on the TTL (time-to-live) of the record in your local arp table, then this will be the right method for you. With my post I wanted to clarify, for other users trying to detect wifi presence, that the above quote from mrEd is technically incorrect. An ARP ...

As I understand the arp -a command only checks the (local cached) arp table of your machine, the phone is not involved.
You can turn off your phone and still get a result out of the arp -a once it is in the arp table.

Thnx Jos, for pointing out that topic.

I'm also specifically 'missing' sunday 27th of March in my graphs. Also running V3.4834
Maybe it has got something to do with the DST change? (Zomertijd)

Bericht namens netbeheerders. 4 jan 2015. Goedendag, Met dit bericht willen wij u namens uw netbeheerder informeren over het volgende: Momenteel ervaren de netbeheerders een storing in de uitlevering van P4-standen bij een deel van de slimme gasmeterpopulatie. De storing doet zich voor op een groot ...

I've also noticed this today. The digital display on my gasmeter is showing the correct milage, that number is still increasing. But the readout from the P1-telegram shows the last milage from 2015. So Domoticz is working just fine. Don't mess with your setup.
