moist-controller VS feature-requests

Distributed irrigation valve controller. Runs off of a 5W panel and charges a 18650 battery, controls a latching sprinkler valve, tubing ESPhome.

Power budget is going to be your main issue, normal sprinkler valves take a lot of current and solar is unreliable. I’ve been able to get an 8266 to run in modem sleep (always available via WiFI) with a 5W solar panel by using a latching DC solenoid and some careful choice of low quiescent current components: check out the repo

Semi-related, check out my distributed valve project. It doesn’t solve the pump problem, but it does solve the low-power and flow monitoring requirements.

Sure, it's part of a Solar Irrigation Valve Controller that I'm working it. It's still a work in progress but the solenoid driver part seems to be pretty much finalized. It's meant to drive a 9V latching sprinkler valve solenoid which draws >1A when actuating, but only for a few ms.

I was hitting “post” when your comment came in :). Solar-powered distributed valve controller

This is the best expliantion of what I'm seeing but the solution the issue was closed with doesnt work for me (the switch.turn_on = I2C_POWER line causes an error). https://github.com/esphome/feature-requests/issues/1511

I found this post on github: Cover, open_duration and close_duration, variables instead of just numbers · Issue #930 · esphome/feature-requests (github.com) The response to the post was:

Yes, use global with restore true. see example here https://github.com/esphome/feature-requests/issues/461

Found this: https://github.com/esphome/feature-requests/issues/1712 looks like documentation is incorrect...

It's not currently supported.

I've had a github issue for ESPhome open for a while on this. Although some possible solutions have been presented, I don't think anyone has been successful.
