This solution assumes there is a display/control unit. However, I have an EcoPart 400, which I control manually on/off using an esp32, so there is no display to connect to.
However the manual for connecting displays (i.e. EcoLogic) says they should be connected using Liycy-cable to ports G51-53.
Could it be possible to connect the esp directly to those instead of to a display? Or does the display do some “translation” of protocals between the pump and display?
I also have a GSi 12, but it’s not working out of the box. Would you be so kind to tell me what you have changed, so that it will work with the GSI 12?
Yes, I got it working! Been working well for about a year now.
I noticed that the registers in the pdfs does not fully match so I spent some time to try and figure out the settings/data I want.
I think I have two ports in the panel, the indoor unit is from ~2016
Have a CTC Gsi 612 that I connected to home assistant via modbus. I have an outside sensor but no sensor inside.
Can you use my usual sensors around the house to adjust the heat (the curve I assume)? Thought of an average value that helps to adjust the heat up or down?
Will probably switch to electricity price per hour, so I’m thinking about if you can somehow get it to produce more heat, for example those hours the electricity price is low to produce less those hours it’s expensive.
With the hot water, I produce a little more when the solar panels provide good power.
Hi!
I’m trying to find a nice solution how to connect my CTC GSI 16 to HomeAssistant. Is this project still up to date or has anyone tried to make HW on Wemos D1 ?
I have the 587057301 Display that has 2 RJ12 connnections in the back and only one connected to the Boiler/heatpump. This is not the display with ethernet/internet support.
Is this project the preferred solution to connect CTC Modbus to Home Assistant ?
Is the second RJ21 connection on the dislpay “modbus-out port” ?
Are there other HW solutions/projects available, either Wemos D1 or even simple Modbus to Ethernet if that’s easier.
I have my router next to the CTC GSi, so cable or Wifi doesn’t really matter.
Why I’m asking for Wemos project is because I have 2 free Wemos D1 boards available.
I know this thread is a bit old, but I’d appricate any reccommendations or help in getting data from my GSI into Home Assistant.
My application have been working super for a long time, but after the latest update of the application and the ESP board, my application have stopped working.
Do some you user have the same problem, is the application not valid any longer?
