Ideal logic combi boiler with mechanical timer swap with electrical

[Dobsuk]

Hi all, i moved recently in new home and realised that there is no room external thermostat wired to the Ideal Combi boiler. There is only mechanical timer on it. I saw some videos on Internet that mechanical timer can be replaced with electrical one but i am not sure if it is compatible with Halo Smart Thermostat or just Ideal Heating Electronic Thermostat. I wanted to upload and some photos but cannot see how. Thank you for your help.
