SSRs don’t work well with digital signals unless they are tiny.Any relay that can handle ~100V DC in NO mode will work.
The advantage of the WeMos relay is that it already has all the circuitry needed to work with 3.3V signals.
There are a bunch for Arduino as well – I have an 8-way relay board I’m using for hydroponics switching.
Like these: 1Ch with optocoupler for 99c. From China, so shipping will be weeks, though.

Or these at ~4x the price for identical unit from the US
