OpenSprinkler Forums Hardware Questions OpenSprinkler Pi (OSPi) Does anyone have a working I2C LCD working? Reply To: Does anyone have a working I2C LCD working?



I have finished my enclosure that includes the LCD,, so now I’m trying to focus on getting the display to actually work. I see that “Sirkus7” made a correction in the MQTT version of his Python code, which is line #75, which reads:

data = data.replace("\"pass\":", "\"password\":") # Replace protected keyword "pass" with acceptable term "password"

I have inserted this in between lines #45 & #46. If you were to export your OpenSprinkler settings to file, you will see that it is a JSON file and in that file, there are the MQTT server username and password. Instead of using the word “password”, it is shortened to “pass”, which is a protected word. In line 45 of “”, it basically loads that JSON into a variable called “data”. This line does a “find & replace” of the word “pass:” with the word “password:” so that it does not create the ValueError. Unfortunately, inserting that line doesn’t solve everything. I now get at TypeError.

TypeError: a bytes-like object is required, not 'str'

Despite changing the word “pass:” to “password:” something within the JSON appears as a string when it should be a “byte-like object”. I am currently at a loss as to how to fix this.
