Hi,

I've had my solar install for a few weeks now and I have been trying to get to grips with Home Assistant.  I have been trying slipx06's Dash and ESPHome code.  I have an ESP32 board hooked up to the inverter. 

I have managed to get so far.  I have the powerflow working and I have started to play with the control settings.  

I am struggling to set the times for the grid charge.  I can turn the grid charge options on / off and change the SOC % and charge power but I cant change the times.

Is it because all the settings that I can change are pulled in as a controls but the clock settings are pulled in as a sensor?  When I click on the time to try and change it I just get the history popup.

Any ideas would be appreciated

 

Hi @JonWarby

You will need to update the ESPHome config and setup additional sensors as input numbers. I don't change my time settings so never configured them. Something like this

 

number:
  - platform: modbus_controller          # 250 System Mode Time 1
    use_write_multiple: true
    modbus_controller_id: sunsynk
    name: "${friendly_name} System Mode Time 1 Start"
    id: sunsynk_esphome_system_mode_time1_input
    address: 250
    value_type: U_WORD

Ah, ok, thank you, so I had it working as designed?  I thought I had messed something up.  I am on an agile electricity tariff that varies from day to day so sometimes on the days where there isn't a huge amount of solar I may need a nightly top up of the batteries and the cheapest slots will vary.

Thank you.  Will look to give that a go tomorrow.

 

 

 

I had a go with this on just the first timer.  I moved the #250 section under the number section of the config file and changed the elements you suggested above.  

After pushing the code it changes the element to a number value.  It seems to drop the : so for example 00:30 is read as 30.  2:30 is read as 230.  

If I change the values on the sunsynk app I can see those changes come through to Home Assistant.

The number is also editable now so I can type in a new number in the time slot.  Whatever number I enter seems to be ignored and after a few minutes just gets refreshed with the value that it's defined in the app.

I think this is the part of the log that is relevant

[11:46:27][D][number:113]: New number value: 200.000000
[11:46:27][D][modbus.number:061]: Updating register: connected Sensor=SunSynk System Mode Time1 start address=0xFA register count=1 new value=200.00 (val=200.00)
[11:46:27][D][number:012]: 'SunSynk System Mode Time1': Sending state 200.000000
[11:46:28][D][modbus_controller:032]: Modbus command to device=1 register=0xFA countdown=0 no response received - removed from send queue

I assume that it's not happy with the value and not accepting it
