Maybe yes and maybe not. One normally should not buy outdated tools when newer tools became available that save you time and provide better quality for the job.
Maybe I already did, or maybe, who knows, CED spoke to me about bringing their timer up to the industry needs...
Anyhow, let me break it down to you. The cost of electronic parts for adding bluetooth support to a device like ced7000 is somewhere around $2..5. The engineering effort is somewhere between 3..4 weeks. At that - they really have no excuse to not have BT added to device they haven't updated in nearly 10 years.
With multiple BT-enabled devices on the market and some of them available for over 3 years already, the CED and PACT will be playing a catch up game now and they choose a tough time for that with the current electronics shortages...
