Doesn't connect to wifi

[Gulaschcowboy]

Hi Lucas,

nice work. After flashing and configuration with the homie app it starts up, but doesn't connect to wifi. Therefore I commented out Homie.disableLogging(); to see what is going on. It starts up until trying to connect to wifi network. After that nothing happens. I did several resets and double checked credentials. AP management doesn't see any connection attempts. Do you have any debug hints?

Hi Lucas,

some update: If I choose a open/free Wifi (Freifunk) it connects and starts transmitting to the mqtt.
But temperature and humidity stay at 0 and lumiosity seems to be reversed :

homie/sens1/temperature/value 0
homie/sens1/humidity/value 0
homie/sens1/light/value 605
homie/sens1/temperature/value 0
homie/sens1/humidity/value 0
homie/sens1/light/value 573
homie/sens1/$stats/signal 38
homie/sens1/$stats/uptime 124
homie/sens1/temperature/value 0
homie/sens1/humidity/value 0
homie/sens1/light/value 602 ---> lux(?) exposed to lamp
homie/sens1/light/value 1004 ---> lux(?) with hand on sensor

About temperature/humidity: If i disconnect the serial jumpers for a while, it starts to transmit at least one (last measured/random?) value:
homie/sens1/temperature/value 10
homie/sens1/humidity/value 13
homie/sens1/light/value 570
homie/sens1/temperature/value 10
homie/sens1/humidity/value 13
homie/sens1/light/value 595
homie/sens1/temperature/value 10
homie/sens1/humidity/value 13

So there seems to be an issue with the internal serial communication.
Actually I had same issue with the original firmware, but I had no time to debug it.

Hey Alex,
the values are correctly read over the Serial connection, i debugged that. I just transfer over MQTT what comes from the atmel IC. I will look into that if and how i need to convert the values.
The problem with the missing values is currently in homie itself. There is this Bug where not more than three Nodes are possible. I'm waiting for @marvinroger to look at that issue since i'm not that deep into the homie codebase.

I added the missing values by misusing one HomieNode for all values. Still need to calculate meaningful representational values for the numbers.
