Ok, again a bit further: For some reason the wt32-eth01 user interface kept being very unresponsive when the pzem-004t was attached to it. Still no clue why. But I managed to get the ethernet connection running (via my ...ENERGY...ETH build), and wired via a CAT cable the UI works like a charm. Afte...

After a quick test I can confirm a couple of things: After programming the address, the EspEasy user interfaces shows a green text "Address programming is done". However that does not mean that it is really done, because the first time I forgot the attach again the wires to my pzem-004t, a...

When looking at the esphome wiki: https://esphome.io/components/sensor/pzemac.html# I see a very important warning: Please note that metering chip inside of PZEM module is powered from AC side and it has to be on during startup of ESPHome device, othervise measure results won’t be visible. Damn, dam...

Hi @chromo23,

Ah that is a good tip. Really appreciate your feedback!
I will try this in a couple of days from now. Need to find some free time first

Morning... I tried to setup the 0xFF but still NaN values: https://github.com/bartbutenaers/node-red-contrib-blockly/assets/14224149/68d59a70-eef1-43e7-b949-2abff3dd6fed I also tried to disable the next setting, but again no luck: https://github.com/bartbutenaers/node-red-contrib-blockly/assets/1422...

I have done some changes, but still NaN values: https://github.com/bartbutenaers/node-red-contrib-blockly/assets/14224149/ce0f7f9d-41bb-402e-b00e-6ce81972019c This is what I tried: Changed software serial to HW serial 1 Used other gpio ports (gpio14 and gpio15) Reversed the diode Tried with and with...

@ath, Ah yes indeed you are right. In our Node-RED discussion afterwards somebody explained that the diodes in the diagram needed to be installed in the other direction (and explained why): https://discourse.nodered.org/t/3-phase-power-consumption-measurement/68489/182?u=bartbutenaers I had totally ...

@TD-er, Thanks for joining (so fast...)! Ok I will try some other ports. Unfortunately there are not a lot of gpio pins available on a wt32-eth01: https://github.com/bartbutenaers/node-red-contrib-blockly/assets/14224149/80bd090c-8931-4441-bae6-4a4c3de3110b I had used the software serial interface, ...

Hi everybody, My first post in this community... I want to measure the energy of my home via pzem-004t devices connected to a wt32-eth01. But it returns NaN for all measured values: https://github.com/bartbutenaers/node-red-contrib-blockly/assets/14224149/f5d52916-3be9-4434-9e71-82f10fb9b71d Note th...
