Not possible to set fan and system mode on bac-002 #86

Hi! First of all thanks for your great job,firmware on my bht-002 devices work perfectly. The problem: From Home assistant with mqtt I can't set the systemMode and fanMode.(on bac-002) Model bht-002 work correctly,but iI think bac-002 cannot be integrated into Home assistant yet. Any ideas or solutions?

JoostHman commented 4 years ago

Just want to chime in here on the issue with the bac-002. The communication via MQTT does seem to work, however systemMode and fanMode do not actually change anything on the termostat itself.

I also wanted to mention that I did the original firmware conversion BAC-002-ALW via Tuya Convert and it worked without problems!

Keep up the great work!

@JoostHman Did you update your topics for all actions including fan_mode topics? I can't test with mine as my situation is a gas boiler and hydronic with no fan coils.

Hi Austwhite, thanks for the quick reaction. I did update the topics, and looking at the MQTT messages I copies below I think that it is working. I also copied the configuration.yaml file below. I still need to sort out some bits but overall it is working except for the systemMode and fanMode,

During this MQTT message exchange my termostat has been on heating (sun icon) all the time while changing the system mode setting via Home Assistant.

These are the MQTT messages.

Hi! I saw that the systemMode and fanMode have not been updated from Wifi Module to MCU. I fixed it in my fork, releas 1.05b https://github.com/fashberg/WThermostatBeca

Please try and give feedback!

Kind Regards Folke

Fantastic, this works now! One question regarding the state flag in the message below. Why would this say "cooling" if systemMode is "heat" what is the purpose? Update: I saw this has to do with the custom hardware modification, this is not an issue.

Thanks a lot :-)

It's now also fixed in version 1.02

Hi @JoostHman

Yes, i guess the setting "Relay at GPIO 5" got enabled. Otherwise this property will not be outputted.

Hi all. am i got it correct: fan control on fw by Klaus works only with HW mod? i can't get it wok iether on my BAC-002ALW... (no HW mod yet)
