I love my Home Assistant install (running on an old laptop with docker)  and have it linked to my Victron setup via colour GX - automations linked to solar are simple at the moment related to when I have excess solar - like linking battery and solar status to geysor status (turns on in day if battery is full).
But once grid tied (hopefully in 2 weeks time) I internd to use it to controll the charge cycles from the grid to minimise/eliminate municipal bill (in PE you can use the grid like a big battery as long as you consume in same time of use period as credit is generated). Battery will get me though the Peak periods in evening and morining. Intend to have a toggle for when there is loadshedding which will make sure the battery keeps about a certain percentage - have thought of pulling in the schedule but not sure I have the skills for that   
Here is a snap shot of live info on my dashboard at about 12:00noon (3kw is being wasted as it has no where to go)  - at moment Geyser and dehumidifier are on because of following conditions, Grid setpoint is 200W:
a) Battery > 95%
b) Family is in town (device tracking)
c) Daylight hours

 

To answer my own question - I have setpoint at 200W and no grid feedback enabled in ESS - no issues with prepaid meter going into tamper mode - waiting for my prepaid meter to be replaced by municipality with grid tied meter to start playing with more settings.... covoid-19 first world problems 

With a E112 current sensor in place (install exactly like Hermans image above)  how quickly is the system able to react when the /grid side loads are high and Victron inverter (Quattro in my case) is supplying part  or most of the load trying to keep Eskom at 0 kwh (battries full and AC out loads not high), and grid side loads suddenly drop. 
My specific concern is the prepaid meter seeing a backfeed and tripping out. I have tried to see what my specific meter would do in this situation but little info avail - is a Itron ACE 9000 ISP.
I had thought of putting the setpoint for Eskom at about 300W to give a bit of a buffer, but not sure that will help if the grid side load drops from say 2.5 kw to 0) or am I worrying about nothing?
To add detail I am wanting to put Oven, washing machine, tumble dryer  and Heat pump on Grid side as they all big users - rest of house on down side of inverter.

@Jakesza - sorry that looks like a glorified remote panel - where the auotmations?  (obvisuly I am more an open system guy)  - just kidding though if it works thats cool
I ve been away from forum for a bit so missed some of the action - some nice dashboards. I ve expanded mine quite a bit in Homeassistant since I posted last. Related to solar I now have a automation which is quite specific to PE Grid tie setup which you might find interesting. If you grid tied you linked to Eskom time of use time periods so you really want to be careful to get your system to only draw from grid in off-peak and standard time. Rate peak is R2.67 vs off Peak R1.24 / kWh.  Now since the Peak is never during high sun conditions you need to be able to tell the system to use battery first during Peak period, then ouside this period you tap into cheaper time periods to recharge the batteries for the next peak. Should mention any excess power fed back to grid during the day can be used as credit in evening as long as the rate periods match - effectively you using the grid as a battery. That way Battery only needs to be sized to house consumption during the 2 peak periods - see power wheel image.
So home assistant keeps track of the rate periods and battery condition and sends a command to my quattro inverter (well actually ESS) to adjust the grid setpoint up or down depending on what rate is active - works like a charm. 
Other toggle relarted to solar is a loadshedding switch - basicaly this tells the inverter to increase battery SOC min to a higher level (mine is 40% vs 20%) - to ensure there is enough capacity in the battries at all times to handle a 2hr unexpected loadshed (have toyed with trying to read the shedules but gave up)
My other dashboards are actaully quite light on the number of switches but I have over 60 automations running eveything from the geyser, robot vacuum to pumps, alarm system and lights. My newest favourite one at moment is I use the passive sensors in my workshop to turn the lights on and of depending on someone being int there - love it.
Have a shipment of Shellys (mostly dimmers and 2 way switch controllers) on their way from Bulgaria, these will convert most of the houses lights that I havent Sonof bassics yet - cant wait  

Sorry about the title - seems to be a forum rib of sorts ?
Anyway here is my install - was quite challenging doing it all myself with little solar experience. Silly things like just getting inverter on the wall (thing ways a ton) , thank goodness for climbing gear and pulleys, made it a steep learning curve. Hopefully the forum wolves will be kind though   .

In case you wondering system is limited that it can’t feed more than 4.6kW into grid.
Things I would have done differently: 
- Bigger fuse boxes & bit more spacing - 35mm2 wire is difficult to bend
- Wider trucking - same reason as above
My average use is 30-35 kWh per day - system is producing 18kWh on average (mid winter) per day - looking forward to summer. The Battery is on paper too small as most use is in evening, however in Port Elizabeth we can Grid tie one to one and we are on Eskom time of use tariffs, so battery only needs to get me through the 2 peak periods, then use the grid as a cheap battery for balance of time.
With the home automation (Home Assistant) tie-in, I manipulate a few things on system via Modibus to optimise the return:
System makes sure batteries are charged for morning and evening peak using grid if needed  - (buys cheaper power or uses credit generated during day). I do this by changing the Grid set point higher for this period. If there is loadshedding (it reads the loadshedding status form Eskom website) - it changes min SOC from 20% to 50% - that way there is enough capacity in batteries to get through any loadshedding episodes regardless of time of day.  Also notifies me of grid failure over google home and on phone

Sorry about the title - seems to be a forum rib of sorts ?
Anyway here is my install - was quite challenging doing it all myself with little solar experience. Silly things like just getting inverter on the wall (thing ways a ton) , thank goodness for climbing gear and pulleys, made it a steep learning curve. Hopefully the forum wolves will be kind though   .  
System :Victron Inverter  - Quattro 10000va /  Victron 250/100 SmartSolar MPPT /  20 x 330 Watt Canadian Solar  / Victron BMV702  / Revov 10 kWh / Venus GX running ESS  / ET112 Grid Meter / Home Assistant Integration. In case you wondering system is limited that it can’t feed more than 4.6kW into grid.
Things I would have done differently: 
- Bigger fuse boxes & bit more spacing - 35mm2 wire is difficult to bend
- Wider trucking - same reason as above
My average use is 30-35 kWh per day - system is producing 18kWh on average (mid winter) per day - looking forward to summer. The Battery is on paper too small as most use is in evening, however in Port Elizabeth we can Grid tie one to one and we are on Eskom time of use tariffs, so battery only needs to get me through the 2 peak periods, then use the grid as a cheap battery for balance of time.
With the home automation (Home Assistant) tie-in, I manipulate a few things on system via Modibus to optimise the return:
System makes sure batteries are charged for morning and evening peak using grid if needed  - (buys cheaper power or uses credit generated during day). I do this by changing the Grid set point higher for this period. If there is loadshedding (it reads the loadshedding status form Eskom website) - it changes min SOC from 20% to 50% - that way there is enough capacity in batteries to get through any loadshedding episodes regardless of time of day.  Also notifies me of grid failure over google home and on phone

Pic 2 - figuring out cable routes - old inverter/ups in green looking sad
 
 
Pic 3 - Old Main Db Board (nice excuse to tidy up)
 
 
Pic 4 - Honey will we have lights tonight ? - no pressure - all stripped out
 
 
Pic 5 - Main Db Looking bit more tidy - split into 2 - Db1 non critical AC loads - Oven and Geyser on Left ELU -  Db3 - Critical Loads -  balance of house - plugs and lights
(Note Inverter feeds back up to DB1 if grid present so DB1 is on Inverter / solar /battery until there is a grid failure)
 
 
Pic 6 - Revov Batteries 10 KWh- server rack box adapted with some additional home made welded brackets (its a 50kg load) - but nicely off the floor

I love my Home Assistant install (running on an old laptop with docker)  and have it linked to my Victron setup via colour GX - automations linked to solar are simple at the moment related to when I have excess solar - like linking battery and solar status to geysor status (turns on in day if battery is full).
But once grid tied (hopefully in 2 weeks time) I internd to use it to controll the charge cycles from the grid to minimise/eliminate municipal bill (in PE you can use the grid like a big battery as long as you consume in same time of use period as credit is generated). Battery will get me though the Peak periods in evening and morining. Intend to have a toggle for when there is loadshedding which will make sure the battery keeps about a certain percentage - have thought of pulling in the schedule but not sure I have the skills for that   
Here is a snap shot of live info on my dashboard at about 12:00noon (3kw is being wasted as it has no where to go)  - at moment Geyser and dehumidifier are on because of following conditions, Grid setpoint is 200W:
a) Battery > 95%
b) Family is in town (device tracking)
c) Daylight hours
