Re: API - When to use nvalue and when svalue? Topic is solved

nvalue is a (single) numerical value, svalue is a string value. In most cases svalue is used because the hardware sends data that consists of more than a single value, which is then stored in svalue as a comma-separated list.

Re: Domoticz fails to start "Floating point exception"

Seems like I'm the guilty party, although of course I could not know that my new evohome via web api class would be re-using a previously registered ID. Is there something I can change that would prevent these crashes?

Re: Timers not always working.

Quite possible that the signal from the rfxtrx is not always reaching the switches. I have several kaku devices myself that don't respond as well to off signals as they do to on signals. Even with the original remote I sometimes need be less than a meter away to switch it off while it will always tu...

Re: some issues with 3.7479

Hi, Yes, there was a user report that gas measurements had shifted to one hour early. As it turns out the gas measurements are recorded in the hour they are received, so if the clock on the gas meter is ahead the (hourly) gas report will be registered to the wrong hour. This is probably less of an i...

Re: P1 Energy Weekly Graphs : Error in calculation

Again: the top (line)graph shows Watts - the second (bar)graph Watt-hours. They're not the same unit and thus you cannot compare them the way you do.

Re: P1 Energy Weekly Graphs : Error in calculation

I'm fairly certain that if you tap the 'Report' button and open up the values for May you'll find that the bar graph is in fact accurate. The thing here is: that top graph is highly unreliable because it does not say how much you used in the last ten seconds, but how much power you are drawing (or d...

Re: Help a lot of Python scripts are killing my memory

Yes. Python is quite heavy on resources. On low profile machines like the Pi you'll probably find that a simple "Hello world" will take at least 30 seconds to run. Perl usually performs a lot better and PHP as well, but if you want top speed you should create a binary.

Re: P1 smart Meter: Gas value readout stays zero

Hmmm, you're right. It does say there should be a gas meter on channel 1. It also displays its serial number (G0032565508865316) but no data. I think there was a previous issue where someone mentioned not seeing any data right after it was installed. You should probably give it a few days. It may be...

Re: P1 smart Meter: Gas value readout stays zero

The gas meter can be on either one of four channels, using a value ID that conforms to the mask '0-?:24.2.1'. As stated before: if such info is known to the smart meter it should replicate that in every datagram. Of course standards exist to be broken, so the fact that the datagram you posted did no...

Re: P1 smart Meter: Gas value readout stays zero

It doesn't. The code simply assumes that there must be a gas meter as well and triggers an automated update if more than 5 minutes have passed since the previous commit.

Re: P1 smart Meter: Gas value readout stays zero

That datagram does not include a gas reading. You could try to catch more of them (note that while you have `cat` running no datagram will reach Domoticz) but AFAIK if a gas meter is connected its data should be in every datagram.

Re: P1 smart Meter: Gas value readout stays zero

From console on your pi, issue the command `cat /dev/ttyUSB0` (or whatever USB sequence number the P1 cable has been assigned). You probably need to be root for this. The data should spit out to screen from where you can do cut/paste.

Re: P1 smart Meter: Gas value readout stays zero

It's actually not implemented yet. You're probably experiencing a chance occurrence related to the time you (re)started Domoticz.

Edit: Oh! wait. Hold on. Different issue. Should have stuck to coffee. Yes, this one is fixed in the current beta.

Re: Gas meter readings changed

I don't have a gas connection myself, but from what I read the gas meter is an autonomous battery operated device that sends its data to the smart meter. I suppose it is possible that its clock could be slightly off, in which case it will depend on the exact times that the smart meter sends its data...

Somehow???

Did you do anything, and if so: what? (e.g. update Domoticz from [oldversion] to [newversion]?)

Re: P1 smart Meter: Gas value readout stays zero

Missed this topic before... The issue is actually not due to the new meter. Most of the code is derived from early efforts to reverse engineer the message content and when IDs change it is usually assumed this is because of evolution. Which it sometimes is, but as it stands the scarce documentation ...
