Kostal Pico in Master/Slave configuration

[Boxer0815]

Hello, is it also possible to integrate a Master/Slave configuration where both devices have a seperate IP-Adresse?

Hey,

mhm I have no information about how that works in your Inverter.

You could run the plugin twice an get the values of both inverters, if that is what you want?

Hi, I tried to run it twice (i added the other inverter with IP-Adress). Unfortunately it is not possible as I can't assign a name to each instance.

You can run two ibstances for different IP addresses easily, but you need to adapt the code a little bit.

Here are the instructions:

1. First install the integration as usual for your master inverter
2. Now make a copy of that folder in the custom_components folder an rename it to, e.g kostal_piko_slave

When this is done change the following files in that folder:

1. change the domain to kodtal_piko_slave in zhe manifest.json, see here https://github.com/sla89/hassio-kostal-piko/blob/74900d8690ff2b4509fd1ed14a70fc0b6fb46ddd/custom_components/kostal_piko/manifest.json#L2 This new domain needs to be used in the configuration.yaml and you will have there something like this:

sensor:
  - platform: kostal_piko
    host: IP_OF_YOUR_master
  - platform: kostal_piko_slave
    host: IP_OF_YOUR_slave

Now the most tricky part:

1. open the const.py file in your slave folder, this one: https://github.com/sla89/hassio-kostal-piko/blob/74900d8690ff2b4509fd1ed14a70fc0b6fb46ddd/custom_components/kostal_piko/const.py
2. search for key="kostal_piko and teplace it with key="kostal_piko_slave - there should be 40 hits. this will rename the sensors to kpstal_piko_slave_XXX.

Ensure config is valid and reboot. Zhen check the logs.

Anyhow it should be easy to extend the integration to support it out of the box but currently I dont have time the next 2-3 weeks.

Thanks a lot - I had also to replace the Sensor name from "Kostal Piko xxx" to "Kostal Piko Slave xxx" in the const.py file. To Identify the Integration I changed in the manifest.json file the name of teh integration to "Kostal PIKO Solar Inverter Slave"

So it is working for you? :)

Yes - perfect!
