Boiler controlling via PWM

[BMA]

Is it possible to use LK to control power to boiler( not only when to start/ends it  but continually controll boiler according to ,for instance, how much battery is charged? I think it is done PWM and SSR (relay) but not sure how much difficult it would be with LK?

PWM (Pulse Width Modulation) could be used to regulate the power input, while an SSR (Solid State Relay) could control switching. The difficulty would mostly depend on the complexity of the logic in LK.
