Espurna: Suggestion - Beok TGT70WIFI-EP Smart Wifi Thermostat

[MariusLaurinaitis]

Hello, what about TGT70 Wi-Fi Series Thermostat ?
GT70WIFI-EP Smart Wifi Thermostat
If it uses ESP8266, can ESPURNA support it?

"If" is used an ESP8266 it could be possible to support it, but ESPurna lacks some features to do so:

• NTC support (easy to implement)
• Display
• Configuration (store minimum/maximum temperature for actions)
• Self contained logic (trigger the load when the temp is below X)

So, it is doable but not trivial...

Hi, this enhancement would be nice and should additionaly be useable for other devices too. Especially the two last points would be nice for e.g. sonoff-devices like a modified Sonoff-Touch with SHT31:

• Configuration (store minimum/maximum temperature for actions)

• Self contained logic (trigger the load when the temp (or humidity) is below/above X)

With this, someone can use every supportetd ESP8266 Device with T/H sensor to controll e.g. the heating/dehumidifier without central logic like openhab.

Best regards

On the same way can be added support for many thermostat. I have a Beca BHT-6000 (Tuya Device). First step is backup original firmware, but how? Here two photos of the device

You will have to wire the pads of the TYWE3S module, see the pinout here: #852. Then there comes the hard work: id all the components it uses and what GPIOs are they connected to and what protocols they use...

Ok, now I'm waiting a second device that i've bougth for tests (the other is already wall mounted and at work), and the ftdi-usb adapter.
When i've wired the pads, is it possible do grab the current firmware and decompile that to get all data?

May be useful: You can control thermostat native via wi-fi with broadlink libraries. It have easy way to integrate with Homeassistant

If is a tuya based device, in homeassistant there is also the tuya component (that works with tuya cloud), is also possible to control the device locally ( https://community.home-assistant.io/t/bht-6000-thermostat-tuya-support/89311 ). That workaround is tested only with bht-6000 thermostat but probably can work with any tuya device.
espurna can be usefull to get better data from the device, example:

• Default firmware does not update target temperature in automatic mode but with custom firmware can be possible
• Default firmware, in local mode, works by request-response logic, but with espurna anything can be pulled-pushed via mqtt

this firmware seems to handle the beca thermostats :
BHT-002-GBLW, BHT-6000, BAC-002-ALW, BHT-002-GCLW

and this one:
Floureon C17.GH3 and MoesHouse BHT-002-GBLW (=Beca ):

Would be really cool if it could be merged into Espurna. :-)

Looking at https://github.com/klausahrenberg/WThermostatBeca/blob/2df063b09bcd5a56616c81802e1ade4b8fc4e5db/WThermostat/WBecaDevice.h#L290 it does look like tuya protocol
