Home Assistant Hardwired using Modbus and Node-Red Part 6: TCP/IP to RS485 Waveshare gateway.

hello everyone welcome to my Channel today home assistant hardwired part 6 rs505 to ethernet Gateway I will be using this Gateway is a non-prov Poe version you can have Poe version so you don't need power supply you can use this uni for example if you don't don't want to use USB stick or another example is if you have home assistant on one of the house and you need to connect couple of rs45 devices on another end of the house and you have ethernet on that side you can just use this unit so basically this unit you can have you have rs485 output this is a power supply rg45 ethernet port this one is basically Poe version so you don't have to use pause power terminals you can use Poe for it then you can download the software for setting up and testing or you can use built-in web server so you just log in to this address and you do you can do your settings so let me go to that web server this is my device name device IP I change it from one to zero that was what the Voice Web Port this is the this this web website port 80 http Gateway IP mode I will always recommend to make it static so now we got the settings so any device which we want to connect to have the settings so basically I will be using the from the previous videos the temperature sensors and the electricity meter would have this settings you must match these settings with the device which we want to connect protocol mod was TCP to Arduino you can change your web login password so let's go to known red okay so I already set up the flow I got connected three devices I got the temperature Community sensor I got eight way acquisition board with one wire temperature sensors and I got one setup for the electricity meter so let's go to configuration this is as usual unit ID very important I got config for the server so let's go to the config okay so type TCP address of the Gateway port and unit ID like best to leave zero because you may use this config settings for various devices so basically you will put that unit ID on your separate nodes and this is this should be just about like I says this is unit ID on the separate notes so let's try it's working I'll clear it and then electricity meter Okay so um in next video I would like to talk about how to connect various devices to the same serial bus Network I'm not gonna talking about this in this video so I think this is all for this video and see you next video
