Hi Gnome,
I've previously tried to use ESP Link on another IoT project, but found it to be a little buggy and not very stable.
If you look at their Github repository, the last update was like 2 years ago, which in terms of IoT stuff means it was abandoned.
Personally, I would recommend ESPHome
The interface is really easy to implement, and you can configure the elements you require quite easily.
 
The following components could be very helpful for your solution:
https://esphome.io/components/uart.html
https://esphome.io/components/mqtt.html
https://esphome.io/components/wifi.html
https://esphome.io/components/web_server.html
Example
https://esphome.io/custom/uart.html
 
Assuming I understand your needs?!

Just some feedback on my battery losing SOC%.
Freedom Won support did a firmware upgrade on the battery today and the SOC is now back at 100%.
The weird thing was that the physical voltage was at 55.8V and showing 80% SOC on the LiBMS page of the Sunsynk inverter, also the same 80% indication on the SOC LEDs on the front of the battery.

This is a gold mine of information. Thank you all for the posts and sharing knowledge.
I'll add my integration for loadsh*tting and managing my devices during these times.
First a grid check sensor in Home Assistant. Add to sensor.yaml or similar under sensors.
#==================== # -- Eskom Status -- #==================== - platform: template sensors: gridstatus: friendly_name: "EskomStatus" value_template: > {% if states('sensor.sunsynk_grid_ct') == "0" %} DOWN/LOADSHEDDING {% else %} UP {% endif %} Then in Node-Red the automation.

flows check if gridstatus sensor is UP or DOWN, and then disables high power devices while load shedding is active.
It will also send a notification to the household phones via Telegram and Home assistant app when load shedding starts and ends.
It also checks the inverter load during load shedding for high usage if another device is using too much power and notify me.
Lastly, the kitchen LED lights is changed to RED even during the day, to remind said household that load shedding is active. 😜 Done via 2 automations in Home Assistant.

Hi All,
Thanx for the responses.
I did log into the PowerForum store and requested a quote a few days ago, but no answer as yet.
I will definitely contact DIYGeek, Inverter Warehouse and Solar shop.
 
Thanx for the feedback. Much appreciated.
