Switching to electric boiler

Options

I had until yesterday a system boiler that did both my hot water and central heating.

I have installed a fischer aquafficient battery water heater and on Monday will have commissioned an 8kW WHBMULTIKW heat only from Fischer. I have a solar array and batteries so electric is more efficient to me than gas.

I have an extension kit, Internet bridge and my hot water was linked to a smart thermostat located downstairs, I also have a smart thermostat upstairs as I had 2 zones on my central heating. I have reduced the 2 zones to one . In addition I have 9 smart radiator thermostats. My question is will the new set up be compatible to my Tado set up or do I need to remove some parts or all of it and use one theromostat provided by Fischer and put my original TRVs back on my radiators? If anyone could could give any advice or guidance it would be much appreciated.
