Daikin firmware update breaks indoor temp readout

[extric99]

Daikin released a new firmware update (1.2.51) several weeks ago that breaks the indoor room temperature readout. Since the firmware update all indoor temps are 0,0. The rest of the functionality seems to unaffected and continous to work fine

I reinstalled the homebrdige container and now nothing is working anymore

http://192.168.0.30/aircon/get_sensor_info http://192.168.0.30/aircon/get_control_info

all above urls return valid info if i try them manually but in the logfile only see

Error getting state: null getTemperatureDisplayUnits: 0 getTargetHeatingCoolingState: 0 etc

Yes, same here. No functionality on the devices that I updated. Any fixes?

Same here after updating the firmware to v1.2.51. No readout of temperature nor any control functions are working. The output of get_sensor_info and get_control_info are still working in the browser:

ret=OK,htemp=23.0,hhum=-,otemp=3.0,err=0,cmpfreq=48,mompow=7

ret=OK,pow=1,mode=4,adv=,stemp=21.0,shum=0,dt1=25.0,dt2=M,dt3=22.0,dt4=21.0,dt5=21.0,dt7=25.0,dh1=AUTO,dh2=50,dh3=0,dh4=0,dh5=0,dh7=AUTO,dhh=50,b_mode=4,b_stemp=21.0,b_shum=0,alert=255,f_rate=5,f_dir=0,b_f_rate=5,b_f_dir=0,dfr1=5,dfr2=5,dfr3=7,dfr4=5,dfr5=5,dfr6=5,dfr7=5,dfrh=5,dfd1=0,dfd2=0,dfd3=0,dfd4=0,dfd5=0,dfd6=0,dfd7=0,dfdh=0,dmnd_run=0,en_demand=0

same problem here

Daikin Firmware 1.2.51 is responding differently to HTTP request. With this version, the host parameter is now case sensitive. The 'request' library sends the http request using 'host' while a browser would use 'Host'.
This has also been discussed here: https://community.athom.com/t/daikin-ai/158/34

@cbrandlehner thanks for debugging. As I am not technical i have no idea if this is something that can be correct by a technical ‘volunteer’. My coding skills are non existent and it would be a shame to let this plugin go to waste

Same issue here.

@cbrandlehner I can't find in the request library source code where HOST is used instead of Host by default, at least in master.

[ronzelver]

I think I saw some lines converting strings to uppercase, that might be the cause of this behavior?!

[kennyadsl]

@ronzelver did you see those lines on this project?

[ronzelver]

No, in the 'request' library.

[cbrandlehner]

I forked this project and adapted it for the new firmware. https://github.com/cbrandlehner/homebridge-daikin-local
