After reading a bit here and there it seems that the issue occurs when the server (inverter?) is overloaded with requests. It happens frequently enough, perhaps 4-5 times per day, during a sufficiently long time (approximately 30 minutes) to be annoying or even dangerous. It can be seen in the figure below (the occasional straight line segments). I'm saying that this can be dangerous because I intend to use a smart EV charger, which relies on the data from the inverter, read at every 6 seconds, to adjust the loading (it could increase it without control if the values become frozen in time).
@saidlm I believe that this issue is because I am using the pocket wifi dongle from solax which tends to be quite unreliable with modbus. Would this plugin work with waveshare products? Also, my serial baudrate is currently set at 115200, should it be instead 19200?
For anyone having connectivity issues with the wifi dongle, I suggest to use a waveshare RS485 to RJ45 Ethernet Module. I've followed these instructions for the assembly, although I have used the device webinterface rather than the vircom software. My configuration is shown below. Hope this helps.
Error as described in the title. The plugin cannot connect to the inverter/read its values. Example debug log below. Pymodbus version: 3.0.0-7 Domoticz version: 2024.7
Seems to be a common/general issue related to pymodbus. Any advice? https://github.com/home-assistant/core/issues/52734 https://github.com/pymodbus-dev/pymodbus/issues/420 https://github.com/thingsboard/thingsboard-gateway/issues/412
