Re: How to use an RPi as a surrogate smart meter?

Although my Iskra MT171 does not create a power consumption number, I have found a way to calculate that and send it to Domoticz. In essence, I start counting time (in seconds) as soon as the Total kWh counter increases, and stop the timer with the next increase. The consumption is than calculated ...

Re: How to use an RPi as a surrogate smart meter?

Hi bbqkees, I don't know much about Domoticz, but from what I do know, I am pretty sure you cannot "just" create meters (with)in Domoticz, because half-smart meters need to be asked to send the data, they use a different comm port with a different baud rate, and the Telegram they blurt out is ...

Re: How to use an RPi as a surrogate smart meter?

Well, a solution turned out to be a lot easier than I initially thought. Let me start by saying first that this is only an exercise in getting something from my meter to Domotics. My half-smart meter does not send out the current consumption, so there is little of value coming out of Domotics if you ...

Re: How to use an RPi as a surrogate smart meter?

Hi emme, Thanks for replying, but note that I'm not using/counting pulses, I'm reading the data coming from the meter. Counting pulses is the only way to get some data out of a dumb-meter. I would call my Iskra MT171 meter half-smart and it has a P0 comm. port. There are four major differences ...

How to use an RPi as a surrogate smart meter?

At this moment, I do not have a "really" smart meter with a P1 RJ-11 serial port. I will eventually get one and by then things should be easy. I think... :lol: However, I am currently stuck with an Iskra MT171 meter. I just installed an optical pick-up with a TTL interface to communicate through the ...

Re: Domoticz reinstall on USB drive; how to keep switch settings

Although this is a pretty old post right now, I thought to document what I just did to make the change from the SD to a USB drive work. I had to collect information from several places. This is my first post on this forum, so please bare with me. I used an 8MB mini USB stick, and wanted to have ...
