Hello, I use Node Red via Home Assistant and when I restart HA my modbus connection to my wallbox is lost. I always get this error in Node Red Log:
[modbus-flex-getter:Send Request] Error: Timed out
I have to restart my wallbox to get connection again.
Does someone know how to fix this issue?
Thanks in advance!
ah sorry, I am from Austria... with wallbox I mean an ev charging station at home
I asked there too but no solution so far
I will try to set up node red in a separate virtual machine and will check if there is the same problem.
Maybe this way I will at least see if it's a node red issue or a Home Assistant issue.
Hi, thanks for your reply
unfortunately a restart of Node-red add-on only does not resolve the problem. still no connection.
I disabled all modbus flows and tried only one send request that I have triggered manually after I restarted Home Assistant and a connection loss. Nothing changed... I don't think it's requesting too frequently.
It's version 14.1.0

I think that is no longer the case. In the
readme it says 16 and 18 are supported from version 5.22 of the node.
you are right .. i must have been thinking of some older issues that the Modbus node was not recovering its connection. Seems to be resolved with the latest versions of Modbus.
@tobik176 Is the Modbus request TCP or Serial rs485 ? if you try with QModMaster do you see the same issues ? Try connecting / disconnecting and reading again.
