Yes, that's the one.
btw, the new firmware that people have been talking about lives at github. romix123/p1-wifi-gateway

diagram from the source https://infi.nl/files/nieuws/_medium/WemosP1Sketch_bb.png The fritz board drawing seems odd, only two resistors installed. But the author also shows his final PCB, which has four resistors. diagram from the second source http://www.esp8266thingies.nl/wp/wp-content/uploads/20...

Thanks for your feedback. I have recently seen that the P1-wifi gateway plug-in is now incorporated in the main branch. However, I have further worked on the plug-in after I had submitted the plug-in to the experimental repository. Keeping things in sync turned out to be hard. I will compare the cod...

Hi, that should not be too difficult to achieve. I do have a version of the firmware that shows the current electricity and gas usage in the LOG on the Espeasy webinterface (therefore also making the device Domoticz independent). These values can easily be piped to a connected Oled. Contact me throu...

I know a bit more about the P1 port (consulted people involved in drawing up the standard). If more than 110mA is drawn from the port, it will limit current output to 50mA until the connected device draws less than 100mA. This sounds like an FPF2000 like load switch is adopted in the meter. I have e...

I am working on getting the EPS8266 based P1-wifi gateway (see romix.macuser.nl to draw its power from the Smart meter, rather than from a separate micro usb power adapter. The DSMR 4.2 specifications rate the 5v power supply (pins 1/6 of the P1 port) at 100mA. The ESP8266 most of the time draws bet...

The PCB, actually a complete unit consisting of the PCB and a Wemos D1 mini, are available at http://romix.macuser.nl

Connect RX and TX, then power up. Release after a few seconds. This will wipe the Flash settings.

I am Ronald. I'm working on getting ESPEasy to behave nicely as an intermediary between the P1 Smart Meter and Domoticz. I've designed a small shield that inverts the Pi comms signals and sits on top of a Wemos D1 mini. Currently sorting out the issues with Ser2Net. I am building a P1 specific plug-...

A bit more background. A client of mine wants to store Smart Meter readings on an SD card, because he does not have a server running to collect the data (trying to persuade him to adopt Domoticz). Adding DS card support for ser2net is easy (adding a couple of lines based on a define in espeasy.ino a...

I have created a small pcb for the Wemos d1 mini to interface it to (Dutch) smart meters. I have included an I2C port for standard 0.96" 128x64 displays. The shields are supported by ESPEasy

See http://romix.macuser.nl

I am using ESPeasy on Wemos d1 mini modules. There is a neat sd-card shield for this module. How hard is it to support piping data to a file on the sd card, to be read/controlled via the web?

See wemos.cc for the d1 mini and its shields.

forgot to include the actual circuit

Hi all, an update. As mentioned I changed plans and have opted for piggybacking on a Wemos D1 mini board. I have also incorporated 2 metering options. The first one is reading the P! port, the second is pulse counting the blinking LED. I have combined two circuits found online for both options. Prob...

Hi Bert, thanks for the comments. I am a bit rusty with circuits.io (123Dcircuits.io, nowadays) and the board and its components are flawed. The diode is supposed to provide polarity protection (I was thinking using a 1N4001). The RJ-11 is meant for a standard phone cable (RJ-11 connectors) to link ...

Hi, Based on Zenit's post on the Domoticz forum (22 Nov 2015, https://www.domoticz.com/forum/viewtopic.php?f=51&t=7815&start=40) on how to connect a Dutch Smart Meter P1 port to an ESP8266 to be used with Domoticz, I decided to design a pcb for the interface. Given that the ESP8266-7/12 have...
