Component esphome.coroutine took a long time for an operation --> Timing issue?!?

[donaldstod]

Hello,

I have been running this code "Victron-MPPT-ve.direct-to-MQTT"on an ESP8266 for months without any errors. HW ESP8266 with a 5V to 3.3V level shifter and the standard pin configuration. After an electrical overstress of the power supply of the ESP8266, it died. After that I saw the new "VictronMPPT ESPHOME" code switched to the ESPHOME version and ever since I never got a complete message from the microcontrollers. I have the code in two setups with different HW both have the same issue. Setup 1: ESP32 with direct connection to the Victron MPPT Setup 2: ESP8266 with connection through level shifter Victron MPPT In both cases I only get either half of the values from the MPPT. Situation 1: Only Batttery voltage, Panel Current, Panel Power... Situation 2: Only error code, Yield today, Yield Yesterday, Yield Total... It seems like the readout of RS232 interface is interrupted by some other routine of the ESPs. Depending on the timing of flashing or read logs I sometimes get Situation 1 and sometimes Situation 2 on both devices. ESP32 has Situation 1 and ESP8266 has Situation 2 in the logs below.

Any help is very much appreciated - thanks a lot in advance!

Ok, sorry going through all other issues I realized this:

victron: id: victron0 throttle: 10s# <-- This uart_id: uart_0

solves the problem at least the messages change from Situation 1 to Situation 2 every 10s. Still a little unsatisfying because with this delay it is a lot less fun to watch it run :-(

[syssi]

Please try the ESP-IDF framework instead of the Arduino one (if you are using a ESP32).

[donaldstod]

Hi syssi,

thank you that erased the warning and I was able to reduce the throttle down to 6s. Is there any possibility to split the publishing into two parts to further decrease the throttle? My wish would be 1-2s throttle to see the MPPT work

[syssi]

I assume printing the log messages is time consuming. Try to set the log level to INFO. This should free many CPU cycles.

Hi syssi, good idea, unfortunately did not help to decrease the throttle time. Situation with the messages is the same, as soon as I go below 6s of throttle I lose values. After programing several times over-the-air, one programming was interrupted and I lost connection to the ESP32, now need to setup everything again. If it is ok for you I keep you updated about the status. Best regards, Michael

All the wiring and timing "problems" let me to switch to this -->[https://github.com/Fabian-Schmidt/esphome-victron_ble] solution. The throttle time is still slower than I would like it, but I don´t have to worry about all the wiring and voltage levels. If you have a SmartSolar with bluetooth and access to a ESP32, the solution above is very nice. @syssi: I saw you also contributed to bluetooth solution - thanks for your great work!
