Feature Request: Read Error Codes / Write Modbus Parameters

If possible, implement reading error codes and allow sending back to MQTT.

I have been reading in other forums that writing to registers is limited, but please implement writing back to the charge controller the few supported parameters available.

Re: mqtt problems

Wow, looks like you already ruled out all of my suggestions. Without a more descriptive debug function that provides verbose failure information, I don't know where to go from here. It's obviously not rebooting due to low power, it is logging to SD card without SD card errors (I used to get those un...

Re: mqtt problems

When you say thousands of pings from mqtt server, what is pinging what? Also check your reboot count after clearing it and running for a day or so. Also, I know you have ruled out power as a culprit, but I was having issues like this and it was power related (issue with my charge controller not supp...

Re: v5.2 Issues - SOLVED

Unit ran perfectly overnight. No errors in web log, web graph is perfect and finally have an indication of when the chicken coop light and automatic door run based on the load current! Not a single reboot either. MariaDB/InfluxDB VM crashed this morning so I lost a few hours of Grafana logs but that...

Re: v5.2 Issues - New Unit

Thank you for the quick reply. It was running fine until the battery voltage got to 13.1v, then started rebooting and missing MQTT. Ran a modified USB cable V+ to pin 6 and the Wanderer USB output, installed an SD card, and now I don't get SD card errors on the web page, the unit is publishing MQTT ...

Re: v5.2 Issues - New Unit

Just noticed the web interface is still updating live values and graph, but after hour, it is no longer publishing to MQTT. I am monitoring using Chronograf importing via Telegraf, MQTT explorer, and Grafana. PingPlotter shows only 1 dropped packet in 1 hour and a -60 signal strength.

v5.2 Issues - SOLVED

I installed the snek unit on a Renogy Wanderer yesterday, and it would not stay running long enough to configure the wifi to connect to my AP after trying for more than 10 minutes. I soldered a 3v programmer to the 3v3 and ground pins on the esp itself and was able to keep it running, and to configu...

Feature Request - Read/Set Parameters

Please add reading/configuring settings. Once I get the dashboard device it will replace the bluetooth module and it would be nice to be able to configure the unit through WiFi.
