S0 kWh meter ID & Topics

[stdioGangsta]

• Connecting a S0 kWh meter to GND and the port marked '1' on the PCB makes it show up in software as Port '2'

• MQTT topics for S0 connected on Port 2 is described in Readme as: panasonic_heat_pump/s0/2, but the status is actually reported on:

panasonic_heat_pump/s0/Watt/2 panasonic_heat_pump/s0/Watthour/2

@stdioGangsta which PCB are you using? The heishamon v3 pcb has s0_1 connected to GPIO12 and s0_2 to GPIO14. Those match the default settings for port 1 and port 2. So I am puzzled for this.

I'll change the readme for the topics

[stdioGangsta]

It's a v2 PCB, According to the schematic it is connected to GPIO12. Still, the heishamon webportal as well as the MQTT topics report the S0_1 port as port 2. Firmware version on wemos is 0.8b.

[IgorYbema]

@stdioGangsta and you have gpio12 set as the gpio for port 1 or port 2 in the settings?

[IgorYbema]

@stdioGangsta Just noticed a design error in the v2 heishamon pcb. Thanks for that! 👍 S0_1 is wired to gpio14 and S0_2 is wired to gpoi12. You can change that in the settings if you like (so change the settings in above screenshot to have S0 port 1 GPIO to 14 and S0 port 2 GPIO to 12)

[stdioGangsta]

@IgorYbema yes, I have exactly the same settings as shown by you. (Well, not exactly, because I use a 1000 imp/kWh counter)

[stdioGangsta]

Great, thanks for figuring it out!
