ESP32 PH & TDS

[Freemaniac]

I am trying to get a Dfrobot PH sensor and EC sensor into HA. Since there are no direct esphome integrations for these what is the best way to bring the values in? Is MQTT the only simple option?

MQTT isn't too bad to add into your Arduino code. I think I would go that route.

Can I hassle you for an example of your MQTT esp32 code. I cannot get the publish function to send calculated values from my sensors.

[LEDG]

Sure thing. Here's my ESP32 code. Mind the noobiness of it.

Feel free to post your code as well and I can see if the problem stands out to me.

That was extremely helpful, made me realize I needed to convert my float values to strings in order for MQTT to publish them.

Thank you!

[LEDG]

Great!

Hi,

without any detail, it is difficult to provide you an answer. At least what kind of code you use and what you have tried so far would be nice to know.

I use ESP32 with SEN0169. There are some examples at GitHub. I used greenponik together with additional ADC.

I posted my code here:
viewtopic.php?f=35&t=5696&start=20

I get an MQTT response. Maybe later I will improve the code.

Hope that helps.
