Support for Sonoff MS01

[stskrp]

Describe the problem you have/What new integration you would like Support for Sonoff MS01 moisture sensor

Please describe your use case for this integration and alternatives you've tried: Sonoff TH10/16 now has support for new sensor - MS01 https://sonoff.tech/product/accessories/ms01/ It is already supported in Tasmota https://github.com/arendst/Tasmota/pull/15335/files But not sure how to port it to esphome. Would be great to have support for MS01 is esphome too.

Additional context

[kahhu3]

I'm using the Tasmota software successfully but would appreciate support in ESP home as well.

Trying to add this through PR#3901 and I'm stuck. I'm getting output, but it doesn't match Tasmota. I'm getting small neg ative values (-3.1) instead of positive values. Other values seem to be close.

[emes30]

Hi @Zebble, I fixed negative values. Tasmota's computations can be negative also. But then we've got this:

if (humidity < 0) humidity = 0.1f;

so I've just added this to your code if (*humidity < 0) *humidity = 0.1f;

and it works.

Hi, Can u send me your yaml, i have the entity but no data. Thx

[emes30]

Here is my fork https://github.com/emes30/esphome/tree/components-dht-ms01 Check it out. If you have entity then your yaml seems ok, check pins and connections.

Hi,

external_components:

• source: type: git url: https://github.com/emes30/esphome/ ref: components-dht-ms01 components: [dht]

switch:

• platform: gpio name: "THR316 Relay" pin: GPIO21 id: relay
• platform: gpio pin: GPIO27 id: sensor_power restore_mode: ALWAYS_ON

sensor:

• platform: dht pin: 25 model: MS01 humidity: name: "Soil Moisture" update_interval: 60s

Here is my yaml, i use ur fork, but i don't have data, just error

[emes30]

What error ? Can you paste your logs here ?

Hi,

does SONOFF MS01 is working with ESPHome now ?

Thank You :)

[toughvj]

hi there, any chance? @emes30 I've tried your solution but it does not work

Pins match, the sensor is connected correctly, what else can I do to make it work? The only possibility that comes to my mind is a damaged sensor, my mistake, I didn't check it on the original software, which I unfortunately deleted :( maybe someone has a backup of the firmware for THR316 that they could share?
