Hi all,

Before coming to MySensors I've been experimenting with waking up my sketches from the atmega328p Timer2, clocked from a 32KHz crystal, instead of waking up from the watchdog timer. This reduces the MCU power consumption from about 4uA to about 1uA while "sleeping". As a result battery life of (coin cell powered) sensor nodes is substantially increased. For example the battery life for a Sensebender Micro, powered from a CR2032, reporting temperture and humidity every minute would (theoretically) be more than doubled.

Now I'm thinking of implementing support for this in MySensors. Regarding this I have some questions:

• Are other people interested in this?
• What would be the preferred way to implement this? I'm thinking of creating a new hardware type derived from the current MyHwATMega328.
• Is there any chance of this being included in MySensors if implemented properly?

Regards,

Ewald
