Time Based Electrolyser Control

What We Control?

We want to start electrolyser for 1 hour every day. We want to automate this.

Objective of Automation

Produce constant amount of hydrogen daily.

Requirements

At least one electrolyser is needed.

Rule

local electrolysers = {
    'D4416F63D6F029A6D88855F157E01CB9',
    '4D6DC302EA88E381A56C15A450F3EDFA',
}

function main()
    if time.is_now_between('15:05', '16:05', TIMEZONE) then
        start_electrolysers(electrolysers)
    else
        stop_electrolysers(electrolysers)
    end
end

function start_electrolysers(els)
    local CAN_START_STATES = {'idle'}

    for _, id in pairs(els) do
        local el = enapter.device(id)
        if el then
            if table.contains(CAN_START_STATES, el.telemetry.now('electrolyser')) then
                enapter.log("Starting electrolyser: " .. el.id)
                el.commands.execute("start")
            end
        else
            enapter.log("Electrolyser `" .. id .. "` not found", "error")
        end
    end
end

function stop_electrolysers(els)
    local CAN_STOP_STATES = {'steady', 'standby'}

    for _, id in pairs(els) do
        local el = enapter.device(id)
        if el then
            if table.contains(CAN_STOP_STATES, el.telemetry.now('electrolyser')) then
                enapter.log("Stopping electrolyser: " .. el.id)
                el.commands.execute("stop")
            end
        else
            enapter.log("Electrolyser `" .. id .. "` not found", "error")
        end
