## TuyaMCU Module (former Tuya Serial Dimmer)
|
||||
|
||||
TuyaMCU module does the job of mapping devices behind MCU to Tasmota devices. TuyaMCU module introduces a new command `TuyaMCU` which maps the FunctionIDs to DpIds. Module supports maximum of 16 configured FunctionIDs.

The TuyaMCU module is for devices employing an MCU to perform the device actions and does the job of mapping those actions to Tasmota commands. The TuyaMCU module introduces a new command `TuyaMCU` which maps the FunctionIDs to DpIds. The module supports maximum of 16 configured FunctionIDs.
|
||||
|
||||
### DpId
|
||||
|
||||
All the devices (relays, dimmers, switches) controlled by MCU are identified by a DpId. Whenever a command is sent to MCU, this DpId dictates which relay or dimmer needs to be changed and same is used when the status is received from MCU. There is no way the Wifi module firmware can know the function of each DpId, so just like GPIO pin configuration for TuyaMCU devices we need to map DpId with its functions.

### FunctionIDs
|
||||
|
||||
The FunctionID defines what type of Device is located at DpId. These functions are similar to default Tasmota GPIOs (Relays, LEDs, Dimmer like PWM, etc). Currently TuyaMCU module supports the following FunctionIDs:

## TuyaMCU command
|
||||
The TuyaMCU command accepts two comma separated parameters; FunctionID and DpId. For example:
|
||||
`TuyaMCU <fnId>,<dpId>`
|
||||
|
||||
TuyaMCU command takes 1 param with FunctionID and DpId comma separated ie
|
||||
|
||||
`TuyaMCU <fnId>,<dpId>`
|
||||
where `fnId` is FunctionID and `dpId` is dpId to map to.
|
||||
where `<fnId>` is FunctionID and `<dpId>` is the DpId to map the function to.
|
||||
|
||||
If any existing entry with same `fnId` or `dpId` is already present, it will be updated to the new values.
|
||||
|
||||
If any of `fnId` or `dpId` is `0` the entry is removed
|
||||
|
||||
If no param is provided then `TuyaMCU` command just prints the current mapping values.
|
||||
If no parameters are provided then `TuyaMCU` command just prints the current mapping values.

|
||||
Example:
|
||||
`TuyaMCU 11,1`
|
||||
|
||||
`TuyaMCU 11,1`
|
||||
This command maps Relay1 (FunctionID 11) to DpId 1.
|
||||
|
||||
Output of TuyaMCU is the current mapping of fnIds and DpIds.
|
||||
|
||||
## Identification of FunctionIDs and DpIds
|
||||
|
||||
As mentioned earlier, the hardware is controlled by MCU and Wifi module sends commands to MCU over serial to control the hardware. Each hardware has a DpId which can be different for different models even for same manufacturer. We need to identify these DpIds.

### Setting up Dimmer
|
||||
|
||||
We need to configure 3 functions of dimmer
|
||||
|
||||
We need to configure four functions of a dimmer:
|
||||
1. Dimming DpId
|
||||
2. Dimming Range
|
||||
3. Power metering if supported.
|
||||
4. Dimming less than 10%
|
||||
|
||||
#### Dimming DP ID
|
||||
|
||||
Dimmer FunctionId is `21`. DpId generally is `2` or `3`. The easiest is to try both
|
||||
|
||||
1. Goto console and type `TuyaMCU 21,2` and wait for it to reboot.
|
||||
2. enter command `dimmer 10` and `dimmer 100`
|
||||
|
||||
If your bulb responds to `dimmer` commands you have successfully configured dimmer function id. Note it for future.
|
||||
If not try id `3` and if even `3` doesn't work keep trying ids from all unknown ids from log till one works.
|
||||
#### Dimming DpId
|
||||
The dimmer FunctionId is `21`. The DpId generally is `2` or `3`. The easiest is to try both.
|
||||
1. Go to the Tasmota web Console and type `TuyaMCU 21,2` and wait for it to reboot.
|
||||
2. Enter `Backlog Dimmer 10; Dimmer 100` in the Console
|
||||
|
||||
If your bulb responds to `Dimmer` commands, you have successfully configured the dimmer FunctionId. Make note of it.
|
||||
If not try id `3` and if even `3` doesn't work keep trying Ids from all unknown Ids from the log until one works.
|
||||
|
||||
#### Dimming Range
|
||||
|
||||
Once you have figured out the dimming function id, we need to find the maximum dimming range. Once dimming id is set, the logs will keep showing like

Now using the hardware buttons increase the dimmer to its maximum and observe the log. The `Dim State=XXX` shows the current dimmer level reported by MCU. Once the dimmer is at max, use this number. Now we need to tell Tasmota to use this as maximum. This controlled by [SetOption43](https://github.com/arendst/Sonoff-Tasmota/wiki/Commands#Setoption43)

We can set it using `SetOption43 XXX` where XXX is the maximum dimmer state reported in logs.

In the `RX Packet` we are interested in the 3 digits before last 2 digits. For example:
|
||||
`98f` in `"55aa03070008060200040000098fb5"`
|
||||
|
||||
1. Make sure the bulb if off at the moment.
|
||||
2. Find out the voltage standard of your country (generally 220, 240, 110v) from [table here](https://www.worldstandards.eu/electricity/plug-voltage-by-country/) For example we have 240
|
||||
3. Multiply that number by 10 (2400) and Convert that number (2400) to Hex using any [hex convertor](https://www.binaryhexconverter.com/decimal-to-hex-converter) which gives you 0x960.
|
||||
4. Now see the number nearest to `960` in the logs. In our case it is `98f`. So we expect thats the voltage which is `ID=6` in our example.
|
||||
5. Set voltage function Id 33 by entering command `TuyaMCU 33,6`
|
||||
|
||||
6. Now set dimmer to 100% by command `dimmer 100` and observe logs.
|
||||
7. Now we need the power rating of your bulb example `9W`. Multiply by 10 (90) and convert to hex which gives us `5A`. Check which unknown ID is close to `5A` in our case is `59` for `ID=5`. This is the id of `Active Power` function.
|
||||
8. Set the active power function id 31 using command `TuyaMCU 31,5`
|

|

|

10. To get current Id, Calculate `Current = Power / Voltage ( 9 / 244.7 ) = 0.0367`. `Multiply this by 1000 = 36.77.`
|
||||
Now convert `36` to hex which is `0x24`. This is closest to `25` which is our current id 4.
|
||||
|
||||
11. Set the current Function Id 32 using command `TuyaMCU 32,4`.
|
||||
|
||||
1. Make sure the bulb if off.
|
||||
2. Find out the voltage standard of your country (generally 220, 240, 120v) from this [table](https://www.worldstandards.eu/electricity/plug-voltage-by-country/).
|
||||
3. Multiply that number by 10 (2400) and Convert that number (2400) to Hex using any [hex converter](https://www.binaryhexconverter.com/decimal-to-hex-converter) (2400 = 0x960).
|

#### Dimming less than 10%
|
||||
|
||||
By default Tasmota blocks dimming less than 10% for dimmers. Some dimmers can handle less than 10% very well.
|
||||
|
||||
1. Turn the dimmer to lowest using hardware button.
|
||||
2. Check the `Dim state=` in logs to see what is the minimum.
|
||||
3. If `Dim state` is less than 10% of maximum range that was set you need to unset [SetOption69](https://github.com/arendst/Sonoff-Tasmota/wiki/Commands#Setoption69) by `SetOption69 0` command.
|
||||
3. If `Dim state` is less than 10% of maximum range that was set, you need to clear [SetOption69](Commands#Setoption69) by invoking `SetOption69 0`.

### Setting up Switches

|
||||
2. Configure Power metering.
|
||||
|
||||
#### Configure number of relays
|
||||
By default, the TuyaMCU module expects a 1 gang switch. There is no way currently to detect the number of relays present in an MCU based switch. We need to tell Tasmota using FunctionIDs 12 to 18 for Relay2 to Relay4. For example, for 4 gang switch we need to set `TuyaMCU 12,2`, `TuyaMCU 13,3` and `TuyaMCU 14,4` if the DpIds for Relays 2-4 are `2`,`3`,`4`.

|
||||
So for 4 gang switch we need to set `TuyaMCU 12,2`, `TuyaMCU 13,3` and `TuyaMCU 14,4` if the DpIds for Relays 2-4 are `2`,`3`,`4`.
|
||||
|
||||
TIP: You can configure all in one go using `backlog TuyaMCU 12,2; TuyaMCU 13,3; TuyaMCU 14,4`
|
||||
TIP: You can configure all at once by using `Backlog TuyaMCU 12,2; TuyaMCU 13,3; TuyaMCU 14,4`
|
||||
|
||||
#### Configure power metering
|
||||
|
||||
Power metering configuration is same as for dimmers. Check the power metering section for dimmers.

### Setting up Curtain Motor
|
||||
The Zemismart WiFi curtain motor uses a Tuya TYWE1S inside the little white dongle as a radio modem.
|
||||
`U1TX` is connected to "USB D+", `U1RX` is connected to "USB D-", and there is a blue LED in the dongle connected to "USB3 R-" controlled by the MCU.
|
||||
To flash Tasmota, we need `U0RX`, `U0TX`, and `GPIO0`. None of which are broken out on the pcb, so soldering or Tuya-convert are useful.
