If you do not need the card's inputs and outputs to be grounded, the power supply can be floating. It all depends on how you use the card.

Hi, You have the latest firmware (1.5). The calibration in progress status is wrong reported, there is no calibration in progress if you did not start one. The two issues that you reported might need a new firmware version which can not be done without the Pi connected to the internet. The...

Hi, It looks like the last firmware changes affect the one-wire bus functionality, give me some time to dig into it.

Try to connect the sensors before powering the card then do not initiate the scan procedure just read the count.

Hi, Do you use 2 wires or 3 wire sensors? We tested 3 wire sensors with success.

Hi, -The Eight MOSFET V3.1 is made with an I2C IOExpander, the switch time is limited by the I2C speed and by the fact that Raspberry OS is not real-time. - Switching 2 or more channels with different commands will increase the delay but you can set the state of all relays in a single...

Please set diferent stack level for relays and mosfets

Hi, A new firmware was released, and there was a problem with the DS18B20 data conversion but also with "megaind" command. Please update both firmware and megaind command.

Hi, Give us few days to dig into it and we will release a new firmware if is the case. Thank you for the bug report.

Usually, on a 3-wire RTD sensor, you have 2 of one color and one of a different color. On the card is drawn a resistor with 3 pins, 2 pins are drawn connected together and there must be connected the 2 wires of the same color and the remaining wire to the 3'th pin.

The card is connected ? What is the stack level settings? It respond to the megaind command ?

If you put the script in cron or run it at few minutes interval from exec node, it will maintain the system time.

It might be an idea to install the library directly without the virtual environment. Open a terminal, browse to the 16relind-rpi/python/ folder, and then run "sudo python setup.py install". This should install the library for the Python interpreter Thonny uses.

This is a possibility since the constant current circuit can not respond instantly, the output transistor might experience some high transient current.

Hi Tony, I did not feel pushed, I tried to give you a solution before we will take care of the problem. Thank you for the complete review but I am not sure we will be able to take care of the list too soon. Thanks again and I hope you did not feel offended by my last post. Alex.
