Hey @stud I think something to note here is that there is a pretty big difference between the components that are being used to control these fans. L298n components really have nothing to do with PWM Optocouplers with appropriate resisters do control PWM L298n really only limit output voltages simil...

Do you have the ability to control the pumps in both directions? If so, an option might be to stop trying to keep prime (liquid in the line) and instead after each use of the pump you could reverse the flow so you are always starting from a known state (no liquid in the line). This way you can prog...

Nice setup Jaysal .
Have you tried with the pumps above the nutes ? That might help . Good luck

Thanks @stud yes I tried them above the nutes and noticed they lost prime so I moved them under and not much difference.

No, that seems very high. Ill check mine when I get home.

Posting this incase anyone has this pH sensor and wants to use it with ESPhome. I had to manually calibrate it but it appears to be fairly accurate. I am using old calibration solution so I think calibration is not super accurate at the moment. The screenshot below is the probe sitting in pH 7 solut...

Looking for some advise on an issue I have been trying solve. My dosing pumps lose prime over time (about a 1 day or so) I have installed check valves on the input tube and the output tube with no luck. I have also switch the position of the dosing pumps from above the dosing containers to below the...

vdelgatto This is typical for the EC probe. The readings will not respond accurately until you complete the entire EC calibration. The pH probe does respond with the correct readings after each command. You can send sensor78-1 cal,? and it will display the current calibration points For the EC it i...

I found how to change the MQTT send interval, in the console you have to change the TelePeriod.

Default = TelePeriod 300 (5 minutes)

I changed mine to TelePeriod 10 (10 seconds)

Hey stud , worked right away however I only configured the SCL and SDA and the readings showed up. I thought I still had to assign the sensors to the GPIO's. The readings seem accurate though. It appears as though Tasmota will only send updates every 5 minutes, is there a way to increase this ? main...

Yes ESP32

I have it working esphome however I think I would prefer Tasmota for ease of calibration. I will give a try shortly and update.

Thanks!
