DS2423 counter

#1 Post by a.g. pennypacker » 25 Feb 2021, 19:16

I have a DS2423 counter for 1-wire net. It has 2 inputs and a battery backup. Is it possible to connect this counter to a Wemos D1 mini?
Its connected to a S0 output at my powermeter.

My wemos has this firmware: ESP_Easy_mega_20210223_normal_ESP8266_4M1M

I had this counter in a 1-wire net before wich i dont use anymore. Sinse it is still connected to my S0 output i thought it would be fun to connect it to a wemos instead

This is how counter are connected to my powermeter today. https://wiki.m.nu/index.php/Inkoppling_ ... C3%A4knare
Sorry for the Swedish in that link.


Could anyone please help me how i should connect and configure ESP Easy.

Hmm the documentation page for the plugin is lacking some in-depth info I guess....
https://espeasy.readthedocs.io/en/lates ... #p100-page

The plugin is included in the "custom" builds, not the "normal" build.
Its label suggests it should be in the "testing" build, but it is later excluded for "LIMIT_BUILD_SIZE" builds, which is... the testing build :(

I wrote that plugin, at least in my home environment it's working fine. You just need to build the image yourself to include it.

You need three wires between Wemos D1 mini and the Dual Counter board:
* +5V to 5V on Wemos
* GND to G on Wemos
* DQ to D4 (GPIO-2) on Wemos, on D4 you don't need an external pullup resistor for the 1-wire bus
