Error: "Unknown message of type bindok"

[find-a-good-nickname]

I get an error when starting this stuff.
npm version: 8.18.0
node version: 16.13.0

}, { r: 200, t: 'bindok', mac: '', key: 'oxk22YP1uj0S97fd' }

...and then silence.
I think that "bindok" is referring to binding is ok, isn't it?

in app/deviceFactory.js this line:
this._setDevice(message.cid, pack.name, rinfo.address, rinfo.port)
sets the id to cid which is empty, so I hacked it to read:
this._setDevice(pack.mac, pack.name, rinfo.address, rinfo.port)
that gets over the binding, but I also had to change:
// If package type is response, update device properties if (pack.t === 'res' && this.device.bound) { pack.opt.forEach((opt, i) => { this.device.props[opt] = pack.v[i] }) this.options.onUpdate(this.device) return }
to
// If package type is response, update device properties if (pack.t === 'res' && this.device.bound) { pack.opt.forEach((opt, i) => { this.device.props[opt] = pack.p[i] }) this.options.onUpdate(this.device) return }
because pack has no v field, but does have p

Please note I have no idea what and why I'm doing, but using these modifications I can use this.

if (pack.t === 'bindok' && this.device.id) {

Because the cid returned by your firmware is empty. Give my fork a try if you like.
My fork is mainly dedicated to supporting sub-devices, there may be problems with single-devices, please feel free to let me know.
