My router reports bytes sent/received as an accumulated integer, and I would like to track the daily usage in Domoticz. I added a virtual "RFXMeter Counter" but every time the router reports usage this is added to the previous total, so yesterday I used (apparently) 18446744073709552000 bytes ...

The answer, of course, is to use MQTT through a Node-Red flow, which makes it dead easy not only to push the UDP data, but also to set up the ASCII encoding function. https://www.domoticz.com/wiki/MQTT Edit: Specifically, my "Encode SMS" function in Node-Red looks like this: var beg = "<<<"; var end ...

In case anyone's interested in using multiple CSI connected surveillance cameras with the Pi, see also this discussion on the Raspberry Pi forums: CSI FPC DIP15 to round cable

F-it, I went ahead and ordered one anyway, the two port version. Hopefully I'll be able to set up a simple switch in Domoticz controlling the GPIO pin which controls the multiplexer, then schedule this to switch between the two attached cameras and email a snapshot from each one every X hours. I ...

In the interest of minimising power usage (my application is solar/battery powered), and getting the most out of the on-board video acceleration, I would like to use only RasPi CSI camera connected cameras - but I want to connect more than one such camera. It seems others have had the same thought ...

I've got a Sierra Wireless 3G/4G modem/router that allows me to send SMS messages by simply throwing it a UDP message. From the ALEOS Software Configuration User Guide : Example: You want to send the following message: “Test message” to phone number (510) 555-4200. To use this feature, convert the me ...

Okay, I have shelved my python scripts for now and I have found that I can get things roughly working with NodeRed and to do it I am using: https://flows.nodered.org/node/node-red-contrib-modbus Because I am using serial I am using mbusd which I just recently discovered and it is working well so ...

@bigcat: Did you get anywhere with the air conditioning & RS485?

I might be interested in putting a bounty up for native RS485/Modbus support in Domoticz, if anyone here thinks they can create it?

I might be interested in putting a bounty up for this functionality, if there are any takers?

Thanks guys, I think @Egregius has a good point, and though @jvdz's code is a reasonable work-around it doesn't use the index to directly select the sensor, which is what I was hoping for. At some point it might be worth updating otherdevices_svalues to allow integer as well as string indexing.

Allrighty, I'll have a poke around with sqlite3 - after stopping Domoticz, and making a backup copy...

I'm quite new to the Domoticz Lua API - how can I read the svalue of a device by index rather than name? All the examples I've seen use the device/sensor name, e.g. otherdevices_svalues["My Sensor"]. I don't like this at all since the name is liable to change, and would prefer to use the device ...

Maybe if the latitude/longitude is stored in domoticz.db then make a script with the following pseudo code that could run every hour Many thanks, that sounds like a viable approach. Since I've already started getting into how the Domoticz scripting engine works I might give it a go. Thinking about ...
