Hi,
is it possible to use the Home assistant platform to visualize data from SW REX core? Do you have any recommendations on the easiest way to read/write data from SW REX core?
Thanks.

@mtomek Hello gentlemen,
can someone please respond to my last question pleas?
Thanks a lot!

@reitinge Hi Jan,
it's been a long time since I had communication problems between Raspbery PI and ArduinoiMega - REXduino. See previous communication problems. I did not make any significant changes in SW.

In the last 2 days, there have been 2 communication failures:

This indicates an error related to the checksum of the 1-wire measurement as explained to me in the previous answer. This could be explained by ordering some 1-wire measurement.

But what I don't understand is that there are a lot of warnings:

What does the warning "REXduino slave warning, code: 1 1" mean please?

Is there a description of all error codes and warnings somewhere?

Thanks a lot.

@cechurat Hi,
it works with the settings see below. I think there will be a problem in the provider and access to the SMTP server. It's still working with "seznam.cz".

@reitinge Hi Jan,
I continuously monitor the system log. None of the errors (49 52, 51 49, 49 50 or 52 51) that I solved last time have come. Errors still occur 52 51. I replaced one of the 1-wire sensors that oscillated the most, so there are fewer errors, about 10 errors a day (see below).
It would not be bad if the system log could list the REXLANG error even with the pin where the errors occur. This would make it easier to find out which sensor has the most errors.
Best regards

@reitinge Hi,
I have currently 6x 1-wire sensors connected. Each sensor is connected separately to Arduino pins 26 to 31. I increased the task period from 1s to 2s. I did that on September 22nd. Today came a new communication error, see the picture below. The serial line dropped out for a moment. Communication resumed immediately. New fault codes have appeared in the system log.
What could have caused it?
Thanks.
Michal

@reitinge Hi,
error 52 51 occurs continuously, see below. I only record "peak" in the graph occasionally, because I archive the data every minute, see the graph below.

@mtomek Hi,
after three weeks, without a communication problem, the communication error came again. The communication error came exactly after the "peak" of the 1-wire Tsolar measurement (see graph below). The "comm_status" of FB Arduino_MEGA2560hex changes from 0 to 1 (0: Arduino not responding, waiting for timeout to try again, 1: Serial port open, trying to initialize communication).
I still get 1-wire measurement errors in System Log ...

This communication error has not yet occurred. Could it be related to that "peak" of measurement?

Thanks.
Best regards
Michal

@reitinge Hi,
it isn´t related to the previous problem. This was solved by deploying the latest version of FB Arduino_MEGA2560hex and the latest library.
But, during panel repairs, I accidentally found out that I have a broken USB cable between the RaspberryPI and ArduinoMEGA. This error did not recur after replacing the cable. So I will hope that this was the problem.
Michal

@reitinge Hi,
I will definitely analyze all outgoing and incoming data into the REXYGEN protocol system as you wrote. Then I'll let you know.

However, at the last communication failure, the states of the communication variables of FB Arduino_MEGA2560hex were as follows (comm_status = 3, err_code = 57, err_subcode = 57). These values have not changed.
The system log had the following errors:

Is it possible to find out what the problem is from this system log listing?

Thanks.
Best regards
Michal
