Why does my smart thermostat keep crashing?

My Tado setup has been pretty solid for years. But over the past couple of weeks the smart thermostat has crashed three times - it is the connection to the boiler, so the whole house goes offline until I can physically reset it.

Why is this suddenly happening? Was there a dodgy firmware update or something? Should I replace the batteries (it isn’t saying they are low)?
