Question: how is this._mode determined?
Closed this issue · 3 comments
I'm working on a port of node-poweredup to Deno, but I'm having trouble determining where the value of this._value in devices such as tachomotor.ts comes from. Could someone please explain to me how that value is determined/received from the hub?
Tachomotor and the other devices inherit from device.ts where the mode is set in device.subscribe:
https://github.com/nathankellenicki/node-poweredup/blob/master/src/devices/device.ts#L145
There is actually a problem with this, see this pull request:
I get that. I mean how does the hub send the value of mode?
We request the hub to set the mode in hub.subscribe here:
https://github.com/nathankellenicki/node-poweredup/blob/master/src/hubs/lpf2hub.ts#L77
Currently we simply change device._mode after sending the request in the line linked above.
If the hub changes the mode successfully it sends a response which we currently ignore, i.e. this

With the changes in the pull request only the response would change the mode.
