Mine works fine with the latest KStars, etc... I do not get the message you get. Have you checked the values in the Indi Meteo tab of the MeteoStation driver? That could tell you if the hardware talks to the driver.
From what I seem to understand, you use the graphing capability of the MeteoStation software (web based if I remember); I do not use that feature and wonder if that could be the source of your problem, unless its hardware related.
I do not believe it is hardware related, it worked perfectly fine up the crash a couple of days ago.
Indi is being kept up-2-date, but I had not restarted this driver. Not sure if there is a relation with 1.8.1
I've tried to load it using Ekos, it's a no go area, keep resetting: Arduino MeteoStation is offline / is disconnected... goes on and on and on.
100% sure that my board is not damaged.
I then used Ekos Device Manager to connect to it, and clicked on connect.
We can clearly see that the board is indeed working correctly as the data is being read.
highlighted in bold before and after connection, values go from 0 to x
This is shortly followed by the child process dying:
I have also got a log, but that contains next to nothing important
