Hey everyone, I wanted to share my experience with sending multiple sensor data via MQTT to my openWB wallbox. At first, I was a bit stuck, but I managed to figure it out with some research and trial and error. Here’s my story:I have three current sensors (phase A, B, and C) that I need to send data to my openWB. The challenge was combining these three values into a single array and sending them via MQTT. Initially, I tried using different code snippets and transformations, but nothing worked as expected. I even tried creating helper variables, but that didn’t solve the issue either.After some time spent Googling and reading through forums, I realized I needed to structure the payload correctly. The openWB expects an array of three float values, each representing the current in amps. The key was to format the payload as [value1, value2, value3], where each value is the negated current reading from my sensors.Here’s the solution I came up with. I used a combination of state transformations and a custom payload template to achieve the desired array format. It took some time, but breaking down the problem into smaller steps helped me understand how MQTT and state transformations work together.I’m really happy I managed to get this working. It not only solved my immediate problem but also gave me a better understanding of how to handle similar data formatting challenges in the future. If anyone else is struggling with sending multiple sensor values via MQTT, I hope my experience helps you out!Thanks to everyone in the community for the resources and support.
