@Yveaux said in serial, Ethernet to MQTT: Of course, but MySensors MQTT gateway runs just as fine when connected over cabled ethernet, as when connected over wifi I do not know that Now on this tool, I do not see much benefit from ethernet to MQTT Still, it is good from serial to MQTT.

Gateway >> Node >> Device >> Metrics Nodes have devices attached and each device has metrics.

I want to share an interesting case about updating the firmware over FOTA.. I have several nodes on a RS485 bus with memory chips. Recently I decided to update the firmware on several at once and ran into an unexpected problem - repeated attempts to update constantly ended up with a checksum error !OTA:FWP:CRC FAIL. At the same time, I usually test all new nodes for FOTA firmware updates before installing. I tried to understand what the problem might be and came to an unexpected result - in my case, disabling the directive OTA_EXTRA_FLASH_DEBUG, which I had been using for a long time, when I first tested updates, helped. After disabling this directive, all firmwares were updated the first time. Very strange, but nevertheless ...

@jkandasa Brilliant - thank you!!!

I don't know why but now OTA works better; I still get quite some NACKs on the gateway but at least most of the times the OTA is successful even with signing enabled. With ACK enabled the transfer speed is at least 4/5 times slower

@jkandasa Great! Thanks for pointing me out. I'll take a look. Regards
