I feel your pain with nodedead.
Have you had a look at my new post about setting up and running thingsboard locally instead of on/in the cloud?
Setup Guide Step 1 Here
I am going to post Step 2 tonight.
There are only the 2 steps
All in all this setup is very simple to use compared to HA, though nodered is still required as it does a dam good job reading the modbus data if you have the correct cables/converters. I am reading data continuously at 0.1 second intervals with no timeout issues at all.
I also have a clean shutdown and reboot routine for the PI4 which runs every 4 hours, that keeps everything nice and clean and have had no more nodered freezes for almost a week now.

Hello guys anyone with problems with your Hubble Batteries please contact me directly via email [email protected] 
There is a batch of batteries that has a SOC and SOH Issue with the Firmware on the BMS it is not a Hardware Problem I need to Send a list of Clients to Hubble so we can Identify who has the problem.
Those that have RIOT Cloudlinks send the Serial number of your cloudlink and the Serial number of you batteries that you suspect has problems to me Please note the batteries with the problems are only the ones between DEC 2021 and MAR 2022 and it is not all of them there are just a few with the Defective Frimware Version as far as we can see it seems to be one batch. Hubble Lithium Promised me that they will do everything with in reason to resolve the problems with that batch asap.
Those of you that have RIOT Cloudlinks has an advantage because the battery can be tested Using the Built in Battery analyzer this will enable us to identify the problematic firmware versions faster those that does not have RIOTS well your batteries may have to be returned to Hubble for the tests..
 

Yes they do run all the time.  The speed vary for time to time as the load ect. change.

Before I went to a solar hybrid system, I had a UPS and did what you describe - just kept a few essentials going during load shedding. It does make a difference.

Now, this depends on the layout of the house, but I found that using two extension leads I was able to back up a fridge, two standard lamps and our entertainment systems. This left one outlet open on the UPS and I had a short lead from that to a double sided socket (OK... a very short extension lead) for charging phones and such. 

What made it all work is a property that all these systems have these days, that they cut over automatically. So the input side of the inverter was just plugged into a wall socket and the box was parked in a corner with the extension leads going around the edges of the sitting room so there was little danger of tripping over them.

But eventually I decided that it wasn't that hard to look into the crystal ball and see that electricity supply was going to be a problem for 2 years at least. And not just load shedding but, in Johannesburg anyway, all the other outages due to aged and overloaded infrastructure. And the price would continue to go up and that made the economic proposition better or at least less bad. Plus I had twice had to restock the deep freeze after long outages (OK, in the short term the insurance pays, but the insurer giveth and the insurer taketh away or else the insurer would not be in business). So I cut to the chase.

Solar isn't cheap, but you have to take a long term view of the costs and factor in the soft value as well - keeping the fridges going, keeping the security system on, being able to help out friends and family who are without electricity.
