My parents have decided on a solar system from Neoom with the following components: STAAK Eco with Neoom. Also included is a so-called BEAAM and a Smart Meter.
We would like to make optimal use of the solar power. Is it correct that Neoom has its own energy management system, which, however, comes with costs (CONNECT energy management)? Furthermore, the compatible devices are limited. We have several Panasonic split-type air conditioners. During the transitional seasons, these should support the existing gas heating system and provide heating in case of surplus energy. The air conditioners are not natively compatible with Neoom (not SG-Ready). We will probably also install a domestic hot water heat pump (SG-Ready). That could be connected and controlled with Neoom, so that in the case of surplus energy, domestic water is heated.
One possible solution could be Home Assistant. However, I haven’t looked into it in depth yet. Unlike other systems, there is no direct HACS integration, right? I’ve only found a few forum discussions. In general, it seems possible to integrate Neoom into Home Assistant.
How difficult is it to integrate Neoom into Home Assistant? How challenging is it to use solar power effectively without prior experience? What I mean is: first, the battery should be charged; once it’s full and there’s still surplus, the domestic water heat pump should use solar power; and if there’s still surplus, the air conditioners (during the transitional seasons) should provide heating.
Is Neoom a suitable system for this, or would it be better to choose a system that has HACS integration?
Is it possible to run both in parallel—Home Assistant and the CONNECT energy management system?
I would be very happy if you could share your experiences with me. Thank you in advance!
Hi,
I am just working around with Neeom and Homeassistant. In brief a few points of experience:
my system ist not set up finally, because the battery has a failure and my easee wallbox is still in the process of implementing.
so as a temporary work araound i installed evcc as EMS in homeassistant and it is working great, specially surplus charging.
therefor I took the needed sensor values from the neoom beaam-Api (that means lokal) and put them into evcc.
all expertise for that I found in the threads you are looking in too. a little bit testing, a little bit talking with an AI and it runs
Real experience with the complete Neoom-Systen I do not have at this time, because it is still not running complete. But I am looking froward…
May be you find some inormations uselfull. And your question? You need some time and the will to work with all this. It is not very complicated, if you basicly know something about HA and Yaml.
I believe this is possible since you are using just the neoom api. What would cause a problem, if you add in home assistant another modbus integration such as Solax. Since modbus allows just one master this would cause problems (or you would have to add a modbus multiplexer hardware),
I decided to get rid of all neoom stuff and added the hacs integration SOLAX Modbus. which is quite more powerful than the subset neoom offers. Besides I dislike their approach of paid subscription and prefer to have my stuff local rather than in the cloud.
I am using HACS custom " SolaX Inverter Modbus" integration, it creates 148 entities.
I am using the TCP/ Ethernet Interface. It requires the IP-address and Port (in my case 502) and the type Modbus TCP. This is how the neoom has been connected in the original installation.
As stated earlier be aware to switch off neeom, because the modbus interface allows for only one master. I wasted a lot of time, not reading this condition!
Your Sofar inverter obviously is somehow available in your local LAN, otherwise neoom device wouldn’t be able to connect. Thus no additional device should be needed. In case you have no documentation on the installation you might figure out the TCP address by looking up your Inverter in the router in the table of connected devices. You need this TCP IP Adress for condiguration of the Solax integration. In the configuration in the frist screen you selext the mode of interface - I assume TCP / Ethernet, in the second as shows the screenshot the IP-Address and Port. In my cas Port 502 - this should be documented somewhere for your SOFAR Inverter.
Thanks for the hints. I think I will take all my values via the lokal Beaam-Api. That is with a latency of 30 sec. much more better than via the solax cloud with 150 sec. and sometimes very old values (5 min.).
I am using the local Neoom-API Inteface. The definitions for the several sensors in configuration yaml I found in the internet. May be this would help: Neoom Beeam Rest API
