    • RE: Max amount of devices able to connect to M5Core2

      @teastain

      Cheers, will deffo go for the 200kg and its cheaper. It's for weighing tubs of water so perfect.

      For the scale could I not just use the Extension Port Module for Core2 as I have a few other things to plug in.

      Also decided to pick up a Stick separately as that will have IR temp sensors and ambient temp/humidity so I can measure leaf VPD without running long wires from the Core2.

      Lastly, if I'm using 2 x DC Encoder Motor Module 4 Channels which use the same I2C (0x56) what can I do about that as the modules fit together?

      Thanks again champ

      You're a champ teastain! Thank ou for letting me know about the M5Stack PaHub 1 to 6 I2C multiplexer!

      So the plan is to buy the following instead of finishing my big box of esp32's, sensors, pumps etc etc. This is going to be the stack so any problems please let me know.

      • M5Core2

      • DC Encoder Motor Module 4 Channels (for pumps) (0x56)

      • DC Encoder Motor Module 4 Channels (for pumps) (0x56)

      • 4-Relay Module

      • Extension Port Module for Core2 (for Grove Sensors)

      • M5Stack AC Power Base

      • Ultrasonic Distance Unit I2C (0x57)

      • NCIR Non-Contact Infrared Thermometer Sensor Unit (0x5A)

      • ENV III Unit with Temperature Humidity Air Pressure Sensor (0x34)

      • CO2L Unit with Temperature and Humidity Sensor (0x62)

      • Scales Unit with 20kgs Range (this isn't I2C?)

      • Grove - Capacitive Soil Moisture Sensor x 4

      I don't think I need an M5Stack PaHub 1 to 6 I2C multiplexer at the moment looking at the above.

      What can I do about the two DC Encoder Motor Module 4 Channels as they are both on the same bus (0x56)

      I already have Altas Scientific PH, EC & OCP sensors (not cheap!),. Now could I add them to this or should I just use a separate ESP32 and solder them in place as they need isolators etc.

      I don't suppose M5Stack is supported by ESPHome?

      @teastain Just found the 4 relay module cheers. This is looking great so far, no soldering etc!

      I have found two devices with the same I2C address, is there a way around that?

      I also have a BLE BME280 in a little plastic case called a Ruvvitag. With ESPHome I can easily get one of my ESP32's to search for the device and take the readings which in Ardino IDE. Is this possible with Flow I think its called (the M5Stack Language) or would I have to compile everything in Ardino IDE which replays the information to Home Assistant for date and automation is done inside Home Assistant?

      With the DC Motor Drive I will be using that for my peristaltic pumps but I require 6 pumps in total. IS it just a case of buying an extra DC Motor Drive and stack them together?

      heers, I ready want to get the stack of items ordered!

      Many thanks!

      I will do that first, I'm hoping it will work.

      Regarding the Scales Unit with 20kgs Range: if I wanted to weight a large box could I use 4 and take the average?

    • Max amount of devices able to connect to M5Core2

      Hello,

      I already have all the parts I need for my hydroponic system but it's all in individual parts and while I don't mind doing it, it will take me some time.

      I am looking at purchasing the following stack:

      M5Core2
      DC Motor Drive
      2-Relay 13.2 Module
      2-Relay 13.2 Module
      EXTENSION-PORT-MODULE-FOR-CORE2
      IC2 to Grove Sensor
      Ultrasonic Distance Unit I2C
      NCIR Non-Contact Infrared Thermometer Sensor Unit
      Scales Unit with 20kgs Range

      Is all the above too much for the M5Core2?

      Many thanks
